Very quick research. Arabs have been in the US for decades. But they were the the good Arabs- the Christian ones. Here, “Lebanese” is a very wide and sloppy term. Many Syrian and Iraqi Christians who came here years ago call themselves Lebanese plus the boundaries weren’t so set 7-10 decades ago
But they were the the good Arabs- the Christian ones.
I know of an Iraqi Christian restaurant owner. He fled when the Shah was overthrown. He was very glad to have left. Gleaned during a passing conversation. We had a couple of very intersting conversations. I haven't been to his place in years.
