He continued the war, he didn't pull out as promised.
Got involved in Syria.
He kept Guantanamo open.
He upped the number of drone strikes. Knowingly killed a 16 year old US citizen who was not an enemy combatant or in a country like Iraq or Afghanistan.
> He continued the war, he didn't pull out as promised.
What he promised: "my first day in office, I would give the military a new mission: ending this war". [1]
That's not the same as "pull out".
> Got involved in Syria.
"Got involved" in an already ongoing crisis, and arguably a direct result of the Iraq war, is not the same as starting the Iraq war. Not even fucking close.
Syria: 2.5k troops [2]
Iraq: ~300k troops [3], and we've been there 20 years.
Like I said, multiply Obama by 100x...
On the remaining points, I'm not claiming Obama was great on these issues. My only claim is that if you think Obama even remotely compares to Bush in terms of the amount of destructive policy the two brought about, you lack a sense of scale and perspective.
If you actually believe this, you grossly lack a sense of scale. Multiplying Obama's actions by 100 doesn't come close to starting the Iraq war.
