From what I understand tourists already in Israel haven't seen too much disruption. An occasional trip to the shelter but that's it. But I take your point. All the more reason for Israel to tell Kerry to pound sand and finish off Hamas once and for all.
Israel will severely degrade the capability of Hamas, but the government of Prime Minister Benjamin Netanyahu is on record as saying that the elimination of Hamas is not their goal. Also the IDF is quoted as saying that they would rather have Hamas there controlling the other smaller Islamic groups.
This is coming from Israel’s government and the IDF.
You are correct. The OP has gone off the rails in fear mongering.
