...apparently Israel has been mobilising weapons/planes and carrying out "manoeuvres" but when aren't they?

Not sure if there is really anything new here, but it would be a nice little diversion away from their cruelty and criminality in Gaza and the West Bank.
And if they did and Iran should retaliate, then it's probably back to "poor little Israel" and the great and the good condemning Iran's unprovoked attack on Israel, just like the last time.
Or has that boat sailed?
