Israeli political and military leaders have warned against the possibility of a major military confrontation with Iran, which wants to deter Israel from disrupting its attempts to build military bases in Syria and Iraq and to construct factories in which Hezbollah can convert its huge arsenal of rockets into accurate missiles. This threat is more acute in light of the American failure to respond to recent Iranian provocations in the Gulf. Israel should adopt an aggressive new strategic approach to meet this threat, in coordination with the US and in consultation with Russia.
