As we know Iran loves to provoke on the world stage and especially Israel during Tevet.
Remember that Tevet tends to have a tendency to provoke you to react when Divine protection is low. Tensions are rising on the nuclear talks and Israel has made it clear that they will not sit back while the world leaders are twiddling thumbs.
It will be detrimental though to act in Tevet. Our might comes from Hashem. Divine protection strengthens in Shevat and is at it's strongest in Adar.
Let's ask Hashem to grant our leaders insight and wisdom not to preempt.
