Stop Bush's "endless war" agreement

I just signed a MoveOn.org petition to the Democrats to use their power (such as it is) in Congress to challenge Bush's "endless war" agreement with Iraqi Prime Minister Nouri al-Maliki to keep troops in Iraq forever (or at least the foreseeable future). Here's the plea from MoveOn:

Subject: Help to stop an endless occupation in Iraq

Hi,
Have you seen the news? President Bush is negotiating a deal with Iraq to keep our troops there indefinitely--it could include permanent bases and a massive military presence for years! Bush is trying to tie the hands of the next president.

Congress can stop him from setting up permanent bases in Iraq and block an indefinite occupation--but they need to hear a groundswell of pressure from us immediately and loudly so they act on this quickly.

I just signed a petition demanding that Congress stop the president from committing to a massive military presence in Iraq for decades. Can you join me?

Thanks
