"Train politicians?? Israel isn't Soviet Union circa 1970."
No, Israel is not USRR circa 1970 but especially with Likud Party it is a reminiscent of ultra nationalists of 1930s, like Spain under Franco or Italy under Mussolini.
Ukraine's foreign policy towards Russia was on the offensive side rather than defensive and Ukrainians paid terribly with their lives. The war with Russia was not to their benefit. On the other hand, Israel is not fighting against an organized army like Ukraine and has many defense tools that Ukraine lacks such as Iron Dome.
To be brief, Ukrainians became human fodder in USA's proxy war against Russia, where Israel only fights for its own benefits with USA's backing. That also explains why Israel is not in NATO because they already have NATO protection without contributing to it.
