A mob set fire to the Saudi embassy in Tehran, stormed the compound and trashed its offices while Iranian security personnel stood aside. This is hardly anything new. The Iranian government has been violently contemptuous of worldwide norms of diplomacy ever since it seized power in 1979. The Iranian hostage crisis, where Islamist revolutionaries held 52 foreign servicemen and women hostage at the American Embassy for 444 days, was just the beginning.

Ten years later they blew up the Israeli embassy in Argentina, also with a suicide truck bomb.
