does it mean the invasion of Iraq and Afghanistan is causing the financial crisis in USA and the whole world.

The invasion of Iraq (Afghanistan had to be invaded post 9/11) is just a factor amongst a myriad of them responsible for the Global financial crisis.

I would say both wars r responsible only for like 5% of the global wahala & maybe 25% of US issues.

for actual causes of the crisis look towards Wall Street and their kangaroo financial shenanigans, Greedy commodities speculators and investors who over heated the markets ($147 oil price & other commodity price spikes).
Americas Credit economy
unsustainable Rapid growth of the Indian & Chinese Economy., etc etc

Also do not discount U & I for whatever unsustainable practices (ecological, economic & co).
