The decades-long shadow war between Israel and Iran has turned into direct confrontation, and the world is still waiting for Israel’s response to a barrage of missiles launched by Tehran.

Meanwhile, the U.S. is investigating the leak of highly classified intelligence documents that reveal Israel’s preparing for a retaliatory attack against Iran. The documents, prepared by the National Geospatial-Intelligence Agency, reportedly include satellite images taken on Oct. 15 and 16 that show the Israeli Air Force conducting exercise drills and repositioning its missiles and weapons.
