Is it our job to make sure other nations are safe?

In my opinion I think that it's not. It's not our job because we're not over
visiting other nations and besides it's not our nation. There are other nations
that are not ours but I think that it might be ours in one way. The way that I
think it's ours is because in my opinion I think that we're the ones that should
be cleaning it and stop littering but other than that I don't think it's ours. Even
if we live here it's not job to make sure that it's a safe country I think that it belongs
to the president. This is my opinion of who the nation belongs to.
