Israel calls up reserves. What can Israel and the world expect?

Normally, the Tzahal (literally, Defensive Armies of Israel)
can call up any one unit of troops one year in three. They can also
call them up for short training sessions in the in-between years.

But The Times of Israel reports that Rav Aluf
Benny Gantz, IDF chief of staff, demanded and got authority from the
Knesset to call up 22 reserve battalions on an emergent basis. He has
called up six of them, and might call up the other sixteen. (See also here.)

Last month, the IDF canceled a tribute to reservists, and then a short-term training session. The reports on both stories blamed “budget cuts.” But now Rav Aluf Gantz has called up more troops to active duty.

Sources told The Times of Israel that Rav Aluf
Gantz is plainly worried about Egypt and Syria. He might have good
reason. The Egyptian regular army has almost lost control of the Sinai.
Arab infiltrators got into the Negev last August and attacked a loaded
bus before the IDF killed them. Some of the infiltrators wore Egyptian
uniforms.

In Syria, 10 people living in a farming village died
from mortar fire from government forces. A UN observer on the scene
told the Associated Press that both sides (government and opposition
forces) have violated the cease-fire that should have taken effect on
April 12.

There's more to this. Why did Rav Aluf Gantz cancel leaves and passes for Passover? And what might he be afraid of? Sure, the Naqba and Naksa Day protest season will start shortly. But Gantz would be deploying his extra troops in the West Bank, not in the Negev and the Golan.

No. He's worried about a replay of the Yom Kippur War.

What do you think is going to happen?
