The more things change...

Remember back when the original debate over the Iraq war and the troop levels that would be necessary to successfully fight it was going on?

[A proposed new plan with reduced goals] would resemble the vision advanced
in December by the Iraq Study Group, led by former secretary of state James A. Baker III and former congressman Lee H. Hamilton
(D-Ind.). A Pentagon study last year concluded that even the more limited
mission would require about 120,000 U.S. troops, compared with about 160,000
today, according to administration officials. But officials said it could be
done with 60,000 to 100,000 troops. (WaPo)

Not everybody does.
