BS! Bush opposed a timetable until conditions on the ground post surge changed the situation and his commanders provided him with their analysis.
Obama changed more than just 3 months!!!!! He was going to have ALL troops out in 16 months! Now, he is leaving upwards of 50k troops their indefinitley. Again, the plan he has now adopted is the one decided on by Bush and the Iraqi government BEFORE Obama was elected and had any kind of say-so.
In fact Obama attempted to sway the Iraqi government from agreeing to anything with the Bush administration regrading withdrawal.
The idea of a timeline for troop draw-down had been being negotiated months before one was established. Obama knew this and so developed a campaign stump that made it appear he and only he had some sort of vision for eventual withdrawal from Iraq...that's history and those are the facts.
