Do you have friends who lost friends in the Iraq and Afghanistan wars? What do you tell them? The wars made us less safe. What do you tell your kids who have to pay for them?
Look, I'm not saying don't act. Sometimes military action is the best option. Just keep your eyes open. Sometimes invading countries that want to be left alone, or increased authoritarianism at home isn't the best idea.
Unlike the victims of al-Qaeda, the casualties of those two wars signed up for the risks. (I could have been one of them if eyesight hadn't kept me out of the military.)
We disagree on whether these wars "made us safer", and I'll also note the effort to quarantine Saddam (the no-fly zone et. al.) prior to the 2nd war wasn't cheap, in lives or treasure.
If the Taliban controlling Afghanistan at the time "wanted to be left alone", they could have delivered Osama and company to us as we demanded. To the extent they weren't complicit and supporting al-Qaeda, they violated Niven's Law 1b: "Never stand next to someone who is throwing shit at an armed man."
And I think the peoples of Iran and Kuwait would find it extremely curious to describe Iraq under Saddam as a country "that wanted to be left alone".
