I specifically remember too how GWB swore that the Iraq and Afghanistan mission would NOT end like Vietnam!
BOOM! You got it!
He and Cheney convinced us that it would be like WWII except Iraq would pay for its rebuilding with oil.
Within the next few years we will absolutely see US helicopters take panicked Americans off from the rooftop of the embassy at Kabul. It will be like the fall of Saigon, only worse.
And I say worse because Ho Chi Minh had no real desire for a caliphate stretching from Europe to China. But the radical islamists want just that. And they may eventually get it, all because Bush did not rally the West to crush radical islam in the days after 9/11.
