United States, the United Kingdom, Germany, and other countries. The United States is likely to intervene, and if the U.S. does get involved, it will likely crash the U.S. stock market and Bitcoin; conversely, crude oil will skyrocket. If Iran truly uses nuclear weapons, then Israel's territory will surely be gone. As for whether it can reach the U.S., it's hard to say, but hypersonic missiles are something the U.S. cannot defend against, and once an atomic bomb is launched, it cannot be intercepted. An explosion in the sky would be even more severe. Right now, the only options are for Israel to ceasefire and surrender, or for the Iranian Supreme Leader to be killed, along with bribing high-ranking Iranian officials to collectively defect; otherwise, a global economic crisis is imminent.
