According to the USA, Iran's retaliation against Israel seems inevitable. There are preparations for an escalation.

The USA is getting closer to Israel again. In the event of a war with Iran, Israel would be involved in a two-front war and would face material and logistical challenges with its military. Israel has not explicitly claimed responsibility for the attack, but Israel has also carried out isolated attacks in Syria and Lebanon in the past and pursued a policy of ambiguity with the countries. Two brigadier generals and five other members of the Iranian Revolutionary Guards (IRGC) were killed in the air strike on the embassy in Syria's capital Damascus at the beginning of April. The attack does not necessarily have to come from the north, where Hezbollah is based, according to Bloomberg's assessment. According to statements from people close to the intelligence service, military installations or Israeli embassies could be the target of an Iranian attack, rather than civilian facilities. The US would support Israel in the face of “any threats from Iran and its proxies,” said US State Department spokesman Matthew Miller.
