Euro slump due to planned Wall Street and Washington’s attack - William Engdahl

Germany's Chancellor Merkel says the Euro currency is at risk and that Europe faces its greatest challenge since the EU was formed.

It comes as stock markets in Europe and Asia tumbled on the surprise news that Berlin was banning types of 'short selling' – where investors profit by betting that shares will drop in value.

The euro is under pressure after nations using it had to pull together to bail out Greece, which is struggling under a massive debt and from strikes that are bringing the country to a halt.

Many say the aid package came too late and that the crisis in Athens may be a prelude to the currency crumbling.

William Engdahl, author and economic researcher, thinks it is the greatest challenge since 1999 when the euro was created.

He said the crisis is the result of an orchestrated attack by the U.S. on the dollar's main rival.

“The whole attack on Greece and the attack on the euro originated from a concerted strategy of Wall Street and US Institutions to permanently cripple or try to cripple the only alternative reserve currency anywhere in the world that can challenge the dollar,” Engdahl told RT.
