I see youtr point , but 3 things to consider:
1) Theres a lot of people that already hate americans, so now they are actively seeking to kill americans. Wont they simply come after you? Which leads to : how do you secure a border in an effective way without being xenophobic?
2) In this day and age, where countries like Iran or North Korea can eventually build atomic bombs isnt it best to keep an eye on them?
3)What about genocide? Like Sudan or Bosnia? Are you for US intervention in these cases?
