Preemptive Implementation

It kind of seems like Bush is trying to implement Obama's foreign policy before Obama gets a chance to do it.  He's agreed to a "time horizon" for withdrawal from Iraq (from an article in The Washington Post by Dan Eggen and Michael Abramowitz):

President Bush and Iraq's prime minister have agreed to set a "time horizon" for the withdrawal of U.S. combat troops from Iraq as part of a long-term security accord they are trying to negotiate by the end of the month, White House officials said yesterday. The decision, reached during a videoconference Thursday between Bush and Prime Minister Nouri al-Maliki, marks the culmination of a gradual but significant shift for the president, who has adamantly fought -- and even ridiculed -- efforts by congressional Democrats to impose what he described as artificial timetables for withdrawing U.S. forces. In recent weeks, Bush and senior officials have hinted that they would be open to "aspirational" goals for removing U.S. troops, as Maliki and other Iraqi politicians have voiced increasing discontent with the idea of an open-ended U.S. troop presence in their country.

and we're talking to the Iranians (from an article in The Wall Street Journal by Jay Solomon):

On Saturday the U.S. will hold its highest-level contacts with Iran since 1979, a marked thaw in the two countries' troubled relationship. At the same time, the U.S. is fine-tuning a package of new financial penalties against Iran that target everything from gas imports to the insurance sector. U.S. and European officials said they will intensify efforts to impose these penalties should their diplomatic drive fail to induce Iran to freeze its nuclear program. The sanctions effort could also include measures to impede Iran's shipping operations in the Persian Gulf and its banking activities in Asia...

but it sounds like the new sanctions will be coming since Iran has preemptively said that halting enrichment is off the table.
