It should be said that Bush has stated repeatedly that US troops will eventually leave Iraq, though we can only wonder what he means by "eventually".
http://www.nytimes.com/2007/01/17/washington/17cnd-hillary.html?hp&ex=1169096400&en=915037d66a9da265&ei=5094&partner=homepage Fresh from a weekend trip to Iraq, Senator Hillary Rodham Clinton this morning intensified her opposition to President Bush’s new plan to send more than 20,000 additional troops to Baghdad, calling it “a losing strategy” and a “very bad mission” and proposing new limits and conditions on the overall war effort.
Her proposal:
did not call for a fixed deadline for withdrawing all American forces, saying only that the troops should leave Iraq “eventually.” Nor did she endorse blocking money for the new troop deployment. Those two positions are favored by many antiwar Democrats who are expected to be a force in the presidential primaries, and by at least one likely rival in 2008, former Senator John Edwards of North Carolina.
Instead, Mrs. Clinton called for capping the number of American forces in Iraq to the total number there on Jan. 1 — before Mr. Bush proposed adding forces. That total is roughly 140,000. She also proposed making a new threat to Iraqi government leaders to force their cooperation: the loss of American funds to train and equip Iraqi forces, rebuild the economy, and, to make the pressure more acute, to provide security for the leaders themselves.
Now that Bush has proposed a message of escalation, Hillary has proposed that the troop level remain the same, while making threats against the puppet US-installed government in Iraq (and seemingly blaming them for all the troubles, not the Bush regime in DC).
She opposes putting any pressure on the government the American people clearly rejected last November, namely the Bush regime.
