"In a statement, the Ministry of Defence (MoD) said the Royal Air Force (RAF) will repel “any airborne attacks within range” of operations in the region.
It is understood RAF jets have flown over Iraq and Syria, not Israel.
PM Rishi Sunak condemned Iran’s “reckless attack”, pledging the UK would “continue to stand up for Israel’s security”. "
The UK sells Israel weapons. The US sells Israel weapons. Unlike other countries, Israel pays more reliably. A good salesman looks after their best customers.
Also, it seems that since Israel suffered no significant damage from the attack, they’re not going to retaliate now. So the support worked, because otherwise there probably would have been more than minimal damge to Israel, they would have responded and we’d have open war between Israel and Iran.
