They don't really have much to gain from trying to grab parts of Syria - they already have just the right amount of territory in the area to have very defensible borders. Taking more would give them territory much more vulnerable to attack, pretty much nothing in the way of natural resources, and most likely a population somewhere between neutral and hostile to manage. Not to mention that it would surely play rather poorly in the Arab world and the greater diplomatic community. Israel has done relatively well to conspicuously have no involvement in any of the Arab Spring rebellions.
And yes, Israel has some extremely good technology. But they also have some pretty fierce enemies. See their incursion into Southern Lebanon a few years back for instance. They also don't have that large of a population. It probably is in their best interest they aren't seen as expansionist.... for the moment at least.
Given the history short (modern) history of Israel and the religious animosity of the neighbors etc. it would be certain to inflame more hostility internationally than Rawanda taking a piece of Burndi for instance. But I'm sure you are already aware of all this. I went back and read your previous posts. It seems you may be looking for an anti-Semite under every rock. Well... next rock. I'm just pointing out practical reality. I don't have an axe to grind with Israel existing.
What made me raise an eyebrow was the bit about how if things changed, it might be in Israel's interests to be expansionist. That's obviously true, one could say that about any country, of course, but... well, in the end that's probably on me being oversensitive, and it was uncalled for to go after it.
Certainly Israel has been very formidable against weak armies such as those of Egypt. However, I don't think Israel's brief 2006 war against Hezbollah went all that well. Very little achieved at considerable cost. https://en.wikipedia.org/wiki/2006_Lebanon_War
My impression was that the average Israeli soldier involved was like: "fuck this, what the fuck am I fighting for?" Shades of Vietnam!
The Israeli army of 2016 is not at all the same as the armies that fought in 1967 and 1973. But I'm not very knowledgeable about this stuff, so I'd welcome corrections.
It's worth noting that Hezbollah is quite terrible at counter-insurgency too, and they know it, which is why they've never made any attempt to take control of the rest of Lebanon outside the Shia area they control in the south.
I was and still surprised they didn't grab a bit of Syria.
If Israel was "hell bent on using nuclear weapons" why haven't they used their nuclear weapons? You are so choked with hatred you can't even assemble a consistent argument. You need to step back and think about things for a while. Ask yourself why you hate so much, and who put this poison in your head, and why they did it.
Eh, there's no reason to be surprised. There is no strategic benefit to Israel in "grabbing" arbitrary chunks of Syria just because they happen to be undefended at the moment. It is in an excellent position right now to not just defend itself against any attacks from Syria but indeed deter them, and military overextension would weaken that.
