20% of Israel’s population is Muslim.
Yes all people entering Israel are vetted no exceptions except for known entities. Usually your vetted at the departure point. I at the time 40y/o white male, blue eyes, traveling to SF on tower air (defunct) was chemically swabbed, just imagine if your headed to Israel, you will be profiled, you will be questioned, your background will be investigated.
If Israel had our immigration policy, Jews would be in the minority in no time. No need to negotiate land for peace any longer. The Muslims would own it.
