Hezbollah fired anti-tank missiles and mortars at Israel Defense Forces positions in southern Lebanon across 15-16 June, hours after the memorandum was digitally signed. 1 The IDF answered with four strikes on the fighters it said had threatened its troops. Hezbollah is the Lebanese Shia militia and political party that Iran has armed and funded for four decades; the fighting eased after the exchange but did not stop, and no Israeli withdrawal followed.
Iranian foreign minister Abbas Araghchi had already set the tripwire. On 15 June he warned that any continued Israeli military presence in Lebanon would count as a violation of the memorandum, building on Israeli defence minister Katz's earlier ruling that the IDF stays "as long as needed" . Hezbollah firing on Israeli troops is active combat, which runs well past the mere presence Araghchi named. By Tehran's own definition the deal was being tested before its text was even public.
Washington described the same clause two incompatible ways inside one weekend. A US official told reporters on 16 June the memorandum was "not conditioned on Israel withdrawing from Lebanese territory" but "envisioned a ceasefire that covers both Iran and Lebanon". 2 One half holds Israel exempt; the other folds Lebanon into the truce. The ambiguity traces to the Lebanon carve-out written into the original mutual halt , the kind of constructive vagueness that papered over past Lebanon truces and works only until someone tests it. Hezbollah firing on 15-16 June is that test arriving early.
