On the issue of "Supporting the Troops"
It is not merely a matter of supporting "current" Presidential policy. In fact, its not really a matter of current Presidential policy at all.
Furthermore it is not simply a one facit issue at all. While "winning" IS part of it, it is NOT merely about "winning".
In fact, one argument often used by the left is, on its face, 100% valid: Never spend the lives of our troops without a compelling issue of national security. (They just always redefine "national security" so troops can NEVER be deployed)
Lefties and Righties aint going to agree on what is a "compelling issue of national security" any time soon.....
Having said that.....
Once engaged, pulling a Vietnam style cut-and-run is NOT supporting the Troops.
Supporting the Troops means supporting them to the best victory possible. Ideally a full 100% victory, but even a partial victory can be good. Today, South Korea is a rather prosperous Asian state. I CAN ONLY IMAGIN WHAT OUR CURRENT DAY LEFTIES WOULD BE SAYING DURING THE DARK DAYS DURING THE RETREAT TO PUSAN.
On 911 the United States was attacked, and NO STATE ON EARTH LAUNCHED THE ATTACK. The lefties would like us to have wimpered in a corner and called the cops, while commenting on why we "deserved it".
Afganistan harbored our enemies. Enough Said.
If you are not willing to TOUGH IT OUT 1950s Chosin/Pusan style, then I don't by it when you say you support the troops.
(I can argue Iraq too, but my points ramble to much as it is....)
