You want perfection. Israel is working on it. The countries buying the Iron Dome do not seem to have the concerns you seem to be having.
Israel claims a 84 % success rate. Why the missiles get through?
Non Hamas terrorist groups get their weapons from whichever way they do, aside from Hamas. Both sneak them all through tunnels and other means.
Nope. Only the explosives are imported. Hamas is making the rockets in their places..
Hamas and the other groups are very much aware as to what will happen to all of them if they insist on starting another war with Israel, which Hamas leaders are promising for next year.
They can do it....at their own risk. Do you think they will take it?
They will be loud, Israel will demolish Gaza again and take the blame. Not very smart. Even the UK has a ban of military exports to Israel, except for components Israel buys for the Iron Dome.
In other words, you do not actually have a Syrian counter terrorism measure to offer to Israel, but just a thread on these forums which talks about it?
Of course, Israel has to react by itself. They could profit from Syrian experience, if they make peace with Syria. It is easy to make peace with Syria:
Assad: Syria to Recognize Israel if Real Peace Offered
Which side is the terrorists in Syria?
There are four major terrorist entities in Syria:
1. FSA (defeated by Syrian army)
2. ISIS (defeated by Syrian army)
3. HTS (formally Nusra, official Al-Qaeda in Syria, controls all rebel-held territories)
4. SDF (US mercs, collaborated with ISIS, controls Syria east of the Euphrates)
