Email to citizens asking for help:
The situation in Israel is still unpredictable; mortar and rocket fire may take place without warning. Please continue to follow the instructions of security and emergency response officials. Commercial flights are available but limited. If you wish to leave Israel, we encourage you to take advantage of those options now. U.S. carriers have temporarily suspended flights to Israel, if you choose to depart, you will need to fly to an intermediate location and book onward travel from there to the United States.
We understand there is high demand from U.S. citizens wishing to depart and the flight options are reduced. In the coming days we hope to assist U.S. citizens with transportation options to depart Israel. Due to the large numbers of U.S. citizens indicating interest in departure assistance, we will plan to offer transit over several days. If you choose to take this departure assistance, transportation may be by air or sea and will be to a nearby safe location and not to the United States. Travelers should be prepared to arrange their own lodging at the safe location and pay for their own onward travel from the third country to their chosen destination. Departure assistance is provided via a loan from the U.S. government which requires travelers to sign a promissory note (an agreement to repay) prior to departure.
Seems like he is asking and suggesting - not demanding. Bet there is always some kind of forms that have to be filled out whenever America goes into another country to take its people out. Cheers!
