I have to say that I am not pro-Israel. Therefore, I don’t see Hamas as an illegal opponent to Israel. Hamas is justifiably at war with Israel because of Israel’s intrusion onto Palestinian land. Throughout history such intrusions are considered acts of oppression and because there is no other remedy, the use of force is justifiable.
“US interests” is a vague term. A US interest is anything the US says is a US interest. The only real US interest which is too often neglected is the happiness of the American people. Anything else is overreach. I guess that’s my version of America first.
