Israel has a strong backing from the US. It is part of their Modus op since early 1900s which is to get a strong backer. Earlier, British was their patron and that’s how they get their foots in Palestine. Sometimes in 1930s or 40s (if I am not mistaken), they managed to get close support from the US, that became their new patron, and they reduced their dependence to the British at that point and even committed terror campaigned against them so that the British wouldn’t be in their way to gain Palestinian territories.
So, why would they care about international pressure/support when the US is with them. It’s not necessary, as the international community won’t be able to do much as long as some powerful body is always be behind them.
