I'd say it already started...the pre-lude was 9/11 attack on America.  Act I was the US invasion of Iraq.  Act II will be a middle east conflagaration around Israel,Palestine,Syria,Iran axis.  Act III - while US is busy defending Israel, North Korea will take the opportunity to invade the South and China will takeover Taiwan...leading to nuclear showdown similar to the Cuban Missile Crisis.  Act IV - will be the breakdown of the "system", loss in confidence of US economy, long gas lines at the pump, Constitutional rights abolished  Act V - the end...who knows how it will end, but Einstein said World War IV will be fought with sticks and stones....
