What is the biggest bomb - not the Greeks who are not going to be allowed to quite the EU -you can no more exit the EU then the Confederacy could exit the USA.
The US project for another war -a preemptive strike before they get nukes and a delivery system . Remember the rule no one who has nukes will get nuked or invaded..
This is the biggest bomb of all -and maybe no one can halt its eventual detonation. Four US banks hold some 95% of US derivatives - a $600 trillion time bomb. The entire worlds yearly GDP is about 65 trillion, just under 11% of the worldwide hidden debt -global derivatives.
