Instapundit linked up this article written by a former green beret with some interesting observations I myself have noticed:

The wonder to those of us who trained to be guerrillas is not that there is so much activity right now in Iraq but so little. If the situation was reversed and our special ops guys were advising the resistance, the entire country would be aflame. A well-trained, organized force supported by a significant percentage of the Iraqi population would have scores of bombings daily along with dozens of assassinations.
...
Criticism is surfacing that President Bush has turned Iraq into a battleground for terrorists. If that is truly the case then, well, good: better to fight them in Iraq where they are isolated, vulnerable and the rules of engagement permit our professionals to engage and eliminate them, than to have to fight them here. If Iraq is the catalyst that is bringing these vermin out of their holes in Syria, Iran, Afghanistan and Palestine, then, hooray, we have achieved yet another tangential benefit by fighting the war.

Read the whole thing, very interesting.
