In the end he or his successor will leave (like all other armies in history) – the only difference being the number of body-bags returned to America.
His justification is that if he does not keep digging The Bin will come back to America and do some more terror.
The Bin could have been stopped before he hit the twin towers.
There was enough intelligence there.
The Israelis knew in advance but forgot to tell us.
The Bin, or anyone else, could be stopped before they try again.
America is now a police state where everything is watched under The Patriot Act.
If the State of Palestine could be sorted out and Israel moved back to the ’67 border then The Bin would have no reason to terrorize America.
In other words – solve the Israeli problem and we will be free.
