Bye Bye Bush Doctrine? Foreign Policy in an Obama White House

Nov. 5, 2008 — -- Under president-elect Barack Obama, the doctrine embraced by President Bush will be retooled at the very least or possibly even tossed out entirely.

What exactly the "Bush doctrine" is has been open to debate, but it essentially boils down to dealing pre-emptively with emerging threats.

That was the argument Bush used to invade Iraq, an argument that proved questionable when weapons inspectors hunting for hidden caches of nuclear, chemical and biological weapons came up empty-handed.

That invasion was at the heart of the Bush doctrine. It has colored everything the president has done in the foreign policy world, and it will color everything the next president does.

Obama has made much of his opposition to the war from the beginning, a war that John McCain supported. The two's views remain starkly different.

Obama opposed the surge of more than 30,000 troops into Iraq and still believes that it failed in its goal to produce a political solution.

Obama says he believes that all troops can be pulled out within a 16-month period after the election, although he would keep a residual force in Iraq and in the region to conduct targeted counter-terrorism missions against al Qaeda in Iraq and to protect American diplomatic and civilian personnel. Obama has never said how large a force would be needed. He is opposed to permanent bases.
