MW13,
1. Ramban says it (Sefer HaMitzvot, Mitzvot that Rambam “forgot”). According to the Or HaChaim HaKadosh (Devarim 30,20) and the Avnei Nezer (Yoreh Deah 454,6)
Rambam actually agrees that it is a mitzva in our time but did not list it as one of the Taryag because of his technical rules for counting mitzvot. Rav Avraham Shapira and Rav Shaul Yisraeli thus ruled that it is prohibited to give land even for peace.
2. I do not think that they need any special provocation. Our existence is provocation. However, if they think that nothing will be gained they will abstain from action. This was proven in the years after the Six Day War when a Jew could walk alone and unarmed in any Arab city without being harmed. They knew what they would do if c”v they were on top and presumed that we would do the same (this inability to realize that not everyone thinks like oneself is, in fact, very common).
3. You copied it over so you bear responsibility unless you are totally deficient in Hebrew.
