Nobody knows, but the west's reaction to Ukraine is going to have an emboldening effect. They know that if they can launch a war, and if they manage to put Israel on thd back foot (not easy to do), the west's response is going to be fairly milqtoast.
That, and the war in Ukraine may create a crisis between Russia and Israel. Israel has condemned the Russian attack at America's urging, (generally Israel has friendly relations with both Russia and Ukraine, I've even read an unconfirmed report that the Ukrainian PM asked the Israeli PM to mediate in ceasefire negotiations between Ukraine and Russia), while Israel is trying to not anger the Russians too much, the Russians can potentially decide to fuck with Israel by allowing Iran and Hezbollah more freedom to operate in Syria, and by closing the Syrian skies to Israeli planes (which Israel will almost certainly not try to contest to avoid an open conflict with Russian forces. Currently the Russians are turning a blind eye to Israeli attacks against Iranian assets in Syria). If that happens Iran is going to par-taaaay in Syria, and the likelihood of conflict in the near future will grow immensely. Currently that doesn't look like the way things are headed, but the fighting in Ukraine isn't over yet, so we'll see.
