The following countries refuse to acknowledge israels existence as a state:
Pakistan
Algeria
Iraq
Lebanon
Kuwait
Bangladesh
Libya
Yemen
Afghanistan
To name a few...
Iran and, prior to the removal of Assad, Syria, had the annihilation of Israel as official state policy!
Several countries undermine or actively oppose Israel, either by funding, hosting, arming, or politically shielding groups like Hamas, Hezbollah, or Islamic Jihad, or by using diplomatic, economic, or propaganda means to weaken Israel's position. Turkey, Qatar for example.
Numerous countries actual leaders express quite openly colonial plans..
Irans goal is a pan-Shi’a Islamic order under Iranian clerical dominance.
Turkey similarly flirts with ideas about a 2nd ottoman empire.
Not to mention dominant organised groups like ISIS, Hamas or the Muslim Brotherhood who call for a full Islamic state from the Jordan River to the Mediterranean and far beyond.
And we're talking about actions, active policy, real world attempts.
I dunno why people get their knickers in a twist about statements of fringe politicians in Israel. There's crackpots in every country.
What's evident is that Israel has never had a policy, nor acted on an agenda to take over other countries. They've only ever acted to secure the safety of their citizens.
For example, with the Golan Heights, Syria were firing at them for close to a decade and people were dying. Israel went to the UN multiple times and asked them to intervene to stop the artillery attacks and all attempts were halted by Russia.
So they took control of it themselves snd miraculously the artillery stopped.
I'm of a pragmatic mindset and the evidence tells me Israel has always tried to mind its own business but if it's being attacked, it will act.
I think people just want to see it a certain way.
