In this instance, Pelosi is 100% wrong.
GWB, and believe me, I can't stand the guy... But, Pelosi is wrong.
Here's why.
GWB does not need an "act of war" declaration by the US Congress to move troops and attack another Land.
Vietnam was not a "war"... Congress did not declare war and therefore it was a "Police Action". The same goes for other conflicts we've had (a list is earlier in the thread)
The President being Commander in Chief of the armed forces CAN order an attack on whomever he so chooses.
Should he do this and people feel it is an "illegal" act... he can then be impeached...
Pelosi while she may not like the fact, can not deny that GWB is the President of the United States (For better and in most instances "worst"), and by that power he can direct military action on anyone he so chooses.
If Pelosi doesn't like it, she should file impeachment proceedings if "W" decides to attack Iran.
That's how it works guys... You may not like him, but in this case... Pelosi is just wrong about what he can and can't do.
It makes me wonder... If she's Speaker of the House and she does not know this... what does this say about her qualifications?
