While on the advance in Ukraine, Russia has recently suffered tactical setbacks in the Middle East. The fall of Aleppo to Syrian rebels is merely the latest in a string of developments — set in motion by the events of October 7 last year — to cause problems for the Kremlin.
Amid the ongoing war in Gaza, Israel has taken on Russia’s partner Iran and its associates in the “axis of resistance” in a protracted tit-for-tat. In the spring, intensified Israeli operations in Syria eliminated scores of Iran-affiliated fighters and weapons. Israel upped the ante in September, unleashing a cyber-kinetic operation against Hizbollah which culminated in the killing of its leadership. In late October, it bombed Iran’s ballistic missile programme and other defence-industrial sites.
