Israel did bomb their Syrian Embassy. This was to be expected.
This goes way further back than this. In 1994, agents of Iran and Hezbollah bombed a Jewish centre in Buenos Aries. An Argentine court has just found Iran liable.

Nothing to do with Zionism. These Jews were living their own lives peacefully in Argentina. Iran ordered them dead for being Jews.
A targeted killing that wiped out a commander in the terrorist IRGC and his associates is peanuts compared to this. Israel could have taken out the entire embassy if they so pleased.
