So why bring this up now? Because it is a good reference point when considering perhaps the biggest foreign policy issue facing the US, the Iranian nuclear enrichment program. It is abundantly clear that while we are headed into the same territory as the controversy over weapons of mass destruction in Iraq in 2003 the current threat is being treated with considerably more respect as a matter of national security by all concerned.
The president has consistently asserted that he would not let Iran develop a nuclear weapon; the reader is left to imagine how that prohibition would be enforced but the assumption is clear. In this respect Likud, Republicans and other actors merely differ on where they would draw the "red line" that would trigger military intervention; some sooner, some later, some whenever Israel says so; but by all accounts we stand at or near the Rubicon.
Just recently an unusually capable drone appeared over the Mediterranean coast of Israel and was shot down:
The leader of Hezbollah claimed today his group was responsible for an unidentified drone that flew deep into Israeli airspace on Saturday before it was shot out of the sky by the Israeli Air Force, and that the aircraft was Iranian-made.
Hassan Nasrallah, leader of the militant Lebanon-based group, made the revelations in a televised address today and boasted that the drone had been able to fly hundreds of kilometers undetected before it entered Israel, then tens of kilometers over Israel before it was eventually shot down.

While noting that "tens of kilometers" isn't very "deep" and Hizbollah drones are not exactly new this one flew a long distance on a complex route to reach its target which was close to some of Israel's more sensitive sites. Then the Patriots appeared:
A Patriot surface-to-air missile battery was deployed in Haifa two days after the incident. Israel Defense Forces officials said that the deployment was not an emergency measure, and that such systems are deployed to the area from time to time.
IDF officials refused to comment on the possible connection between the drone, which was intercepted on Saturday, and the Patriot missile system deployment.

Aggregating the uncertainties of the Syrian civil war, the renewed threat of rocket attacks from Lebanon or Gaza, the continued deployment of significant military forces in the Gulf, the conflicting claims of the existence or imminence of an Iranian nuclear weapon "break-out" and the strong rhetoric from the Israeli leadership one would be forgiven concern and elevated sensitivity to indications of escalating conflict.
