Israel has every right to block those hostile to it
Every country has the right to decide whom they allow to enter. We may or may not agree with their reasoning, but that is irrelevant. A sovereign nation is well within its rights to determine the conditions for itself.
This is certainly applicable in the case of Israel barring U.S. Reps. Ilhan Omar and Rashida Tlaib from entering their country. Furthermore, the fact that these two women have demonstrated an open hostility toward Israel makes an even stronger case for this action.
By the way, I have yet to hear any major criticism for Saudi Arabia’s longstanding policy of restricting access to Medina and Mecca, which is based entirely on the basis of one’s religious choice (only Muslims may enter these cities.)
Once again, we have a classic case of vilifying Israel, while another country gets a free pass for imposing conditions on any potential visitors.
