Are they going to have their own Airforce and Navy? Are the Jews of Judea and Samaria going to in effect, have their own nations. The Egyptians do and they have the most modern and sophisticated weapons.
You have to understand something. The mentality of these Muslim animals is not to put all of one's eggs in one basket and use a ton of air force to try and quash a bunch of Jewish settlers. Rather, they would think, "Ha! We'll get our rag tag team together and they can quash them easily." And sure enough, they make that move and they'll see what the small number settlers can do to their more numerous army men...
It's like this. Why didn't Russians attack Israel in 1948 to help the Arabs? Weren't they much more powerful? Because they saw how a much more outnumbered Israeli nation totally destroyed 7 surrounding Arab nation.
How do you think the slaves of Egypt were able to defeat the Cannanites and surrounding nations?
If the settlers were well armed they would win battles...and it would freak out the Arab enemies...and regular Israelis would see how they win battles and will demand the IDF to fight like the settlers...
It will take the settlers to show the rest of the ISraelis what it means to be a winning prideful Jew instead of a loser self hating woody allen Jew.
