MW,
1. There is no halachic requirement to go without a smoke detector. There is a halachic requirement to assert our sovereignty over all parts of EY. Personally, I would be satisfied with a total ban which would also apply to Moslems and Xtian tourists. However, being that Moslems are allowed and some poskim allow and even encourage Jews to go up Jews should also be allowed
2. Those who blame the architects of Oslo for the second intifada are making the opposite argument. They are saying that appeasement always has the opposite effect. This is not only true regarding Jewish=gentile relations. Neville Chamberlain’s “peace in our time” is the classic example.
