This is actually easily explained by Israel having an intimate role in US foreign policy and culture for the past 80 years instead of being a majority Muslim constituent republic of the Soviet Union!
Korea, Japan, UK, Mexico, Canada, etc all are tightly entwined with the US and its culture. The first 3 had major roles in opposing the USSR. Politicians aren't taking trips to any of those countries en masse. Nobody is having their visas canceled for criticizing any of those countries. No college is losing funding if someone complains about those countries.
