USA ceased to be a superpower in 2008. American dollar does not deserve to continue as reserve currency. American budget deficit continues to grow. Extension of Bush-era tax cuts means there is no hope of deficit coming down in the next two years. With 600 billion dollars being printed dollar will weaken further. USA may not remain a great power.
For USA to remain a great power it has to cut its expenses. It should stop fighting useless wars in Afghanistan, Pakistan, Yemen and Somalia and call back remaining troops in Iraq.
USA should open its borders to Mexicans. That will provide labour and demand for houses will go up.
Troubles in eurozone prevented euro from becoming an option as reserve currency. Russia and China have agreed to accept each otherâ€™s currency. Many countries are likely to follow suit and dump dollar.
Brazil is rising as a power. In Security Council it refused to vote against Iran. It has recognized Palestine. It won bids to host Olympics and Football World Cup.
China is a rival to USA. It has large presence in Africa. It supports North Korea.
Military might is not enough to be a superpower or great power. USSR had military might. With disintegration of USSR there was no rival to USA. In 1991 USA went to UN Security Council which voted 12-2 for Gulf War, with China abstaining. In 1999 there was no Security Council vote. USA led NATO in bombing Serbia. In 2003 there was no unanimity in NATO about Iraq War. USA attacked Iraq with few countries supporting it.
Empires rise and fall. No country can remain a superpower for ever. Fall of USA was inevitable.
