bet365 free bets as a form of security cooperation between countries，Widely present in the practice of international relations at all times and at home and abroad。The Book of Rites states that “a promise is called an oath，Come to sacrifice and call the bet365 free bets”，The first chapter of "History of the Peloponnesian War" mentioned that Athens and Sparta had a "wartime bet365 free bets"，Indicates that alliances were a common form of inter-state relations in ancient China and the West。Alliances are also full of vitality in contemporary international relations，In the post-Cold War era，Can the bet365 free bets survive、Issues such as how to transform have attracted academic attention and discussion，bet365 free bets research increasingly needs “the way of adhering to the past”，To protect today’s existence”。In this context，A new book "bet365 free bets Research: Theory and Cases" written by Ling Shengli, associate professor at the Institute of Relations of China Foreign Affairs University，A comprehensive and in-depth analysis of bet365 free bets theory and practice。This book focuses on the formation of alliances at the theoretical research level、Management、Transformation and differentiation，Covers the core content of bet365 free bets theory；At the case study level, take the Asia-Pacific bet365 free bets system and some bilateral alliances built by the United States as examples，Formation of bet365 free bets、Analysis of current situation and trends。This book is also based on the cutting edge，Carry out research on "quasi-bet365 free bets" and other issues，And organically integrate how China responds to alliances with other countries into each chapter，Analysis of the reasons for China’s non-alignment and China’s peripheral security strategy，Has the characteristics of “self-centered” research。

　　The security logic of bet365 free bets formation

The author thinks，The stronger the country is，The more obvious the “security” of its interests is，The greater the corresponding security requirements，The need for bet365 free bets becomes stronger，This reflects the security logic of bet365 free bets formation。Under this logic，Meeting security needs will inevitably increase countries’ demands on the international system，Countries will seek to gain international dominance，bet365 free bets is an effective way to achieve this goal。As a case，The author demonstrates that the United States abandons the "rejection of bet365 free bets" policy，The historical root is the rise in strength，Changes in demands for the international system，To avoid specific countries from posing direct or potential threats to their international status，Turn to actively build an bet365 free bets system，To meet their security needs。

This security logic helps to better explain the theory of bet365 free bets formation。About the formation of the bet365 free bets，Traditionally there is a balance of power、Balance of interests、Three types of threat balance theories。The relationship between international dominance and bet365 free bets formation derived from this security logic in the book，It is helpful to understand the perspective of "defining security with power" in the balance of power theory。The security logic of bet365 free bets formation emphasizes the correlation between national strength and the "securitization" of interests，Help to sort out the relationship between elements in the theory of balance of interests。Meanwhile，This logic also contains the premise that there is a security threat，Can be used as an analytical perspective of threat intent，The characteristics of focusing on security needs are also consistent with the cognitivist analysis path of threat balance theory。

　　Adjustment path to bet365 free bets dilemma

The dilemma of the bet365 free bets is an important clue throughout the book，Management and transformation are the adjustment paths to bet365 free bets dilemma。When the security threats to the bet365 free bets change dynamically，The bet365 free bets needs to conduct internal management to adjust to the bet365 free bets's difficulties，The book uses the US-Japan bilateral bet365 free bets as an example to illustrate this normalized adjustment path；When security threats change qualitatively，The core variables of the bet365 free bets evolve accordingly，Adjusting to the bet365 free bets dilemma is more difficult，The bet365 free bets needs to adapt to the reality through transformation，The book also uses the transformation of the U.S. Asia-Pacific bet365 free bets as an example to illustrate this fundamental adjustment path。In addition，The author also studied bet365 free bets differentiation through wedge strategies，Wedge strategy is to intensify the bet365 free bets’s dilemma，Making security relationships between hostile alliances difficult to maintain。bet365 free bets differentiation is intended to make it difficult for hostile alliances to maintain by leveraging bet365 free bets dilemmas，A counter-adaptation to the bet365 free bets’s dilemma。

The bet365 free bets dilemma and adjustment path explained in this book can be used to analyze the reasons for the collapse of alliances。Academic circles have many explanations for the reasons for the collapse of the bet365 free bets，Strategic adjustment is considered an important factor affecting the collapse of alliances，The origin is the dilemma of the bet365 free bets。The bet365 free bets’s dilemma is like a thick layer of haze，Drives the bet365 free bets to "clear the clouds and see the sun" through various adjustment paths。If the bet365 free bets is not properly adjusted，The dilemma of bet365 free bets members being “implicated” or “abandoned” will become increasingly prominent，Security cooperation between countries will be difficult to sustain，The bet365 free bets will collapse from this。Therefore，Special attention needs to be paid to bet365 free bets dilemmas in bet365 free bets research，Use this as a clue to analyze the internal and external problems of the bet365 free bets。For the bet365 free bets itself，Accurately adjust to different levels of bet365 free bets dilemmas，Attention should also be paid to preventing counter-adjustment to the bet365 free bets’s predicament through differentiation methods such as wedge strategies，Maintaining the security relationship of the bet365 free bets。

　　Alternatives to security cooperation

Alternatives to security cooperation outside the bet365 free bets are also the focus of the author。“Union-like” as a possible alternative to alliances，Has some functions of the bet365 free bets，But more flexible，Can be divided into quasi-alliances、Issue bet365 free bets、United Front and Four Categories of Partnership。The author thinks，The bet365 free bets will transform into a more inclusive direction in the future，To adapt to the actual needs of safety practice。China adopts a security cooperation plan of “partnership without bet365 free bets”，Proof that the partnership China has built is in line with its own interests，is a better form of international security cooperation。Of course，Partnerships have their shortcomings，Use your strengths and avoid weaknesses，To maximize its effectiveness in security cooperation。

Looking at the current situation of international relations, we can see that，Security cooperation programs no longer only refer to security issues，The trend of extending the security field outwards is increasing，The interactive relationship between security and development and other fields is also more significant。For example，The bet365 free bets function is considered to be extended to various fields besides security，The issues involved in “quasi-alliances” such as issue alliances have also expanded to other fields。No matter what security cooperation plan each country adopts，Both should pay attention to the organic connection between security and other fields，Coordinate relevant areas when formulating security cooperation plans，Promote comprehensive and sustainable security。

Overall view，This book is a masterpiece worth reading in the field of bet365 free bets research，What is slightly lacking is the slight lack of attention to the collapse of the bet365 free bets。bet365 free bets disintegration is a weak link in current bet365 free bets theory research，The academic community needs to pay attention，Thus making the system of bet365 free bets theory more scientific and perfect。Looking to the future，Quantitative analysis methods may play a more important role in bet365 free bets research。Academic circles have previously discussed bet365 free bets viscosity through quantitative analysis、Issues such as bet365 free bets performance and other matters，This book also uses quantitative analysis thinking to establish an indicator system for bet365 free bets transformation。Follow-up research may try to apply quantitative analysis methods more widely to other related issues of bet365 free bets theory，Diversify the methods of bet365 free bets research、Integrated development。

As it says in the book，Alliances are an important form of international security cooperation。Security issues run through the entire process of bet365 free bets formation and development，bet365 free bets research essentially explores the approach to international security。Alliances as an ancient but still vital thing in international relations，It will not disappear from the stage of history anytime soon。Stone from other mountains，Can attack jade，In-depth expansion of bet365 free bets research will help our country properly respond to external bet365 free bets challenges，Be more prepared when building inclusive partnerships。Therefore，It is necessary for the international relations academic community to further deepen the study of alliances，For continuous exploration, trustworthiness and harmony、Contributing to international security by being kind and good to neighbors。
