JERUSALEM (AP) — Israel is building up its strike capabilities amid growing anxiety over Iran’s nuclear ambitions and appears confident that a military attack would cripple Tehran’s atomic program, even if it can’t destroy it.

Such talk could be more threat than reality. However, Iran’s refusal to accept Western conditions is worrying Israel as is the perception that Washington now prefers diplomacy over confrontation with Tehran.

The Jewish state has purchased 90 F-16I fighter planes that can carry enough fuel to reach Iran, and will receive 11 more by the end of next year. It has bought two new Dolphin submarines from Germany reportedly capable of firing nuclear-armed warheads — in addition to the three it already has.

And this summer it carried out air maneuvers in the Mediterranean that touched off an international debate over whether they were a “dress rehearsal” for an imminent attack, a stern warning to Iran or a just a way to get allies to step up the pressure on Tehran to stop building nukes.
