"Truce" and Democratic talking points

The right wing is getting a lot of hey from this offer of Bin Laden asking for a truce or whatnot. It shows Bush's war is working, and it has implicit connotations of liberals who would seek peace. Here's what I think the proper liberal response would be.

Would we make a truce with Lee Harvey Oswald, or the DC sniper? No.

Would we make a truce with Stalin or Pol Pot, or if possible Hitler? Yeah.

What's the difference? You make treaties with heads of state, not criminals.

Osama (and the problem of terrorism) should be dealt with that way. He is a criminal who follows no agreements, has no tangible power-base, and would be quickly replaced if he individually conceded.

Terrorism is a police problem.
