Israel on Wednesday implemented an initial, limited call-up of reserve forces and deployed additional anti-missile batteries to the northern border in anticipation of a Western military strike against neighboring Syria.
On Tuesday, Prime Minister Benjamin Netanyahu broadcast a short video sternly warning Syria against attacking Israel in retaliation.
"Israel will be set on fire" if the West attacks, a senior Syrian official told Iranian media, reiterating threats that the Assad regime has been making for months.
The additional Iron Dome anti-missile batteries along the northern border will help to block more, but not all of the missile Syria could send Israel's way if America, Britain and France decide to launch what they are saying will be a focused aerial campaign against Assad's forces.
Israeli military leaders continue to advise that the chances of a serious Syrian attack against Israel are very small. Assad knows that pulling Israel into the war would only further decrease any hopes that his regime would survive the conflict.
At the same time, this is the Middle East, and anything is possible.
