Based on the past history of the Holocaust, America’s avoidance of any action to help these poor innocents in the genocidal rampage they were trapped inside. America owes a moral obligation to aid in their protection now.
The relationship with Israel benefits the US as well. So many medical miracles currently saving tens of thousands of Americans were discovered by Israel.
Israel has also been responsible for protecting our people by providing us with the most reliable information about what our enemies are planning,and in this way stoping planned attacks before they have happened.
