Yep, wholeheartedly agree. I'd be tempted to directly tie it to their desire for new F-15s, as in no F-15EXs until all of the retired Patriots are in Ukraine.
tbh considering how many Israelis hold dual Russian nationality and harbor sympathies to Russia, Israel should be considered entirely suspect. Tech sales/shares/transfers need to be monitored much more closely now.
about those patriots in specific though...
They have M901 Launching Stations and MPQ-53 Radar Stations. They can employ Standard, PAC-1, PAC-2, and GEM. The radar might be able to be upgraded, but it won't be worth upgrading the launchers to M903. The systems are very very old. You basically have to throw away a bunch of things but they are still good it's just they are again very old. They can do mostly AAW and some limited BMD stuff.
