Israel now has a perception that the US represents its "golden hour". In the U.S., Trump and the pro-Israeli team have all the power without brakes. The question of how Israel will use it now is not an issue for Israelis. They believe that there is no point in worrying. Trump has come to power. He is now in a proactive position of acting for Israel, giving the country carte blanche. The same will soon begin to happen with respect to China. As for Ukraine, it is secondary/tertiary to him. His stated position on Ukraine now and will continue to change due to internal US/Republican and external factors.
Trump can teach everyone a big lesson. He is indescribable in his certain determination to raise the stakes. IMHO Iran is really the first target. And it would be just fine, wonderful and great for Israel, for Israel, for the US, for the EU, for all of Western civilization.
Israel fears the alternative: an Iran with nukes under China's wing. Israel believes that China already has one court rabid dog - the DPRK, there will be a second - Iran.
And Iran cannot rely on Russia; Russia will not sign a treaty with Iran on defense in case of a nuclear strike. And in a conventional war, a consolidated strike by Israel and the U.S. military will cut Iran down to the roots.
Iran is the preparation ground to trap and ruin the US. Israel is a primary target for Arabs, but to China, Israel is wholly uninteresting.
This will be the end of the 2nd cold war. China, along with all the powerful military attack dogs it has built up to function independently, will destroy vast amounts of US forces using Iran as bait. Western civilisation will be torn between antisemitist nationalism, democratic humanism and their traditional orientation of anglo zionazism, as the costs of the war and economical penalties keep mounting.
With US tied down and politically devastrated, China does not necessarily even need a direct Pacific war, just like US didn't need direct war with the USSR to take over eastern Europe. China could gunboat diplomacy through Asia, holding Japan and Korea hostage with firepower. With a demand to industrialized Asia like "cut off trade with US over their atrocities in the middle east, or else get wiped out", the situation in US will go from faltering to pandemonium. No more electronics, no more shipping.
The West will be made an agrarian "paradise" again... Never to challenge the East more. This is the long term end result of winning the industry war, China will have great freedom in choosing how to tie down and destroy US in detail.
