Bush and Obama

Apparently Bush recently adopted a new strategy that involves attacking targets in the Tribal Areas without Pakistani permission. http://www.nytimes.com/2008/09/11/washington/11policy.html?_r=1&hp&oref=slogin Didn't Obama get hammered by the right a few months ago for saying that he would do just this? I believe he said that he would attack a known Al Qaeda meeting in Pakistan even if the Pakistanis declined to approve the attack. Am I missing something here? These Tribal Areas seem analogous to N. Vietnam, with Pakistani military and intel leaders acting as China did in the Vietnam war. Both would be difficult to conquer by invasion, due to guerrilla activity and a landscape that supports such activity. Of course, the fact that the Tribal Areas are a part of Pakistan makes them even more problematic than N. Vietnam was. An invasion would surely provoke further support for the guerrillas by their state backers or even a direct confrontation with that state. But, without an invasion the cross-border attacks continue indefinitely and threaten the stability of their target. Unfortunately, American operations in the Tribal Areas will probably turn the Pakistani people against us and could destabilize Pakistan.
