i can kinda see the argument from both sides, basically pulling out early (that's what your dad should've done...no hate...i just had to say it...lololol) would've saved american and iraqui lives but the downside to that is we would've not finished what we started
now i'm not sure which way would've left the country in better shape, basically we ruined the country by invading, not that it was fucked up before, so i'm not sure if it was worse before or after we invaded, but either way it was like destroying a house with the purpose of re-building it and if we'd pulled out it would've just been like leaving the house unfinished. now, after several years and lots and lots of money, the house remains unfinished and we're stuck in a hole. so basically the argument could be we need even more time to finish what we started or we should've just ditched it earlier to save money and lives
