The White House has instructed the Pentagon and the U.S. military to put on hold a transfer of Hellfire missiles that Israel had requested during its recent operation in the Gaza Strip, the Wall Street Journal reports.

According to the report, during Israel’s Operation Protective Edge, White House officials were dismayed to discover how little influence they wield over the topic of Israeli arms shipments, against the backdrop of the U.S. government’s unhappiness with the widespread damage inflicted upon Palestinian civilians.

[A]gainst the backdrop of American displeasure over IDF tactics used in the Gaza fighting and the high number of civilian casualties caused by Israel’s massive use of artillery fire rather than more precise weapons, officials in the White House and the State Department are now demanding to review every Israeli request for American arms individually, rather than let them move relatively unchecked through a direct military-to-military channel, a fact that slows down the process.

According to a senior U.S. official, the decision to tighten oversight and require approval of higher-ranking officials over shipments, was intended to make clear to Israel that there is no “blank check” from Washington in regards to the U.S.-made weapons the IDF makes use of in its Gaza operations.
