• Hitler and Mussolini Rome-Berlin Axis ( Rome-Berlin Axis, 1936) and then with japan Tripartite Pact ( 1940) of.
• This increased instability in the world and the possibility of war increased.

6. Appeasement policy and weak responses

• Britain and France sought to placate rather than prevent the aggression of Hitler and Mussolini.

Unbalanced Global Politics

Unbalanced Global Politics: Detailed Analysis

• The countries of the Middle East (Saudi Arabia , Iran , Iraq) have huge reserves of oil , due to which these countries remain influential at the global level.
• Many large countries intervene in these areas due to their need for energy resources.

• Powerful countries like America and China influence the economy , politics and policies of weaker countries.
• Weak countries have to change their policies according to the wishes of powerful countries.

(ii) Military alliances and the possibility of war

• Unbalanced balance of power leads to the formation of military alliances and situations of conflict arise.
• NATO​ And Russia An example of this is the growing tension between the two.
• China and America The battle for supremacy in the South China Sea is also a result of this imbalance.

(iii) Inaction of international institutions

• the United Nations ( UN) may fail to maintain global peace because big powers take decisions according to their own interests.
• United Nations Security Council ( UNSC) There are only 5 permanent members ( P5 – US , Russia , China , France , UK) , who can stop any decision by “veto power”.

• Powerful countries ignore the environment to expand their industrial activities.
• Developing countries have to pay a heavy price for climate change , while big countries spread more pollution.

3. Possible solutions and improvement efforts

(i) Strengthening the global balance of power

• weak countries to their Increasing economic , military and technological capabilities Is required.
• Multilateral Diplomacy should be promoted so that the voices of all countries are heard.

(ii) Reform of the United Nations and international organisations

• Reform of the United Nations Security Council ( UNSC) should include new permanent members (like India , Brazil , South Africa) and
• IMF and World Bank.

(iii) Reducing global economic inequality

• Small and developing countries should be made self-reliant by providing trade and technical assistance.
• ” South-South Cooperation ” should be promoted , in which developing countries increase trade and cooperation among themselves.

(iv) Preventing military competition and arms race

• More international treaties should be implemented to limit nuclear weapons.
• Military alliances should focus on peace and development , not on conflict.

(v) Maintaining environmental balance

• All countries should make joint efforts to tackle climate change.
• Big countries should take concrete steps towards reducing their carbon emissions.

4. Conclusion

Unbalanced global politics gives rise to conflict , inequality and instability in the world. Big powers use their military , economic and diplomatic power to put pressure on smaller countries.

• 1905: Albert Einstein E=mc3 Introduced the equation which made it clear that mass can be converted into energy.
• 1938: German scientist Otto Hahn and Fritz Strassmann by Nuclear Fission Discovered , which made it possible to create the atomic bomb.
• 1942: In America Manhattan Project started , whose aim was to make the atomic bomb.

2. World War II and the use of the atomic bomb
