Kurds tho...

There are probably a lot of good people in North Korea, still not our allies.

Very different situations. The Kurds are a distinct group of displaced individuals, who have been fighting for us against ISIS for years and losing lives so we don't have to. If that isn't an ally, I don't know what is.

They have no choice but to fight ISIS. They should be glad we even helped in the first place. It isn't our place to fight wars that don't affect us or our true allies. Sorry, we are not going to deploy troops and spend a lot of money for the rest of our lives for wars that aren't ours.

We also died for them as well. We just realize how pointless it is trying to stop these conflicts that aren't ours. 

...You don't think IS affects our "true allies"?

Bullshit.

Clear bullshit.

Also, drawing a line between "true allies" seems like it could easily devolve into some pretty gross areas.

As long as you protect your borders and do a thorough background check on people who come to your country you should be fine. Especially those who come from dangerous Countries.

That is incorrect. Individuals can be radicalized without leaving the county, and further, background checks may not be able to detect all radicalized individuals. When allowed to roam free, terrorism can be tremendously dangerous; even more so when such terrorism is allowed to gain power. Establishing allies in the Middle East is pivotal to protecting the United States and our allies.

My question still stands.

At what point does somebody become inhumane for not expecting the US to be involved in foreign matters?

Following the news or not, this type of thing is on the news virtually 100% of the time over the last 50 years. Somewhere in the world, some horrible inhumane thing is occurring.

So...at what point does the US become obligated to help these people or be seen as inhumane?

Terror within can be reduced greatly by having great security inside our nation and doing our job reporting suspicious activities.
