His WSJ fired a warning shot across the Democrat’s bow. He concluded:

We are at a critical moment in Iraq–at the beginning of a key battle, in the midst of a war that is irretrievably bound up in an even bigger, global struggle against the totalitarian ideology of radical Islamism. However tired, however frustrated, however angry we may feel, we must remember that our forces in Iraq carry America’s cause–the cause of freedom–which we abandon at our peril.

Remember that Lieberman ran supporting the war despite the fact that all his Democratic colleagues were running on anti-war platforms. He risked his Senate seat and the wrath of the Democrats on principle. The Democrats should take the warning shot very seriously.
