Here’s what various government ministers under Bibi did and were not fired (or even publicly reprimanded):
Speak at an event where the image on the podium is of another sovereign country being erased and conquered by your own
Attend a party hosted by a major figure in organized crime who is trying to muscle his way into political power
Say about a country with which Israel just made peace that you don’t like it and would never go back there
Call on the IDF to wipe out an entire village
Get convicted of repeatedly stealing from public coffers
But here’s what Bibi just fired his Minister of Defence for:
Saying that in light of how the judicial reform is tearing the country apart and causing serious harm to the ability of the IDF to protect Israel, it should be paused for a few weeks while an attempt is made to reach a compromise.
In other words, the Minister of Defence was fired for doing his job of watching out for the security of Israel.
Bibi used to be a great prime minister. But the problem with people who get drunk on power and narcissicism is that they reject any disagreement as unacceptable disloyalty, and they become willing to burn everything down around them in order to further their own selfish interests.
You are massively downplaying the seriousness of Gallant's comments. He undermined the government's position on a matter of critical importance an the eve of an historic vote. Whether you agree with the governments position or not, this was an extreme act, especially as it was done when the PM was out of the country. In addition, Gallant legitimized and even encouraged insubordination in the army by saying that that was the reason he was calling for a delay. Would you compromise with your adversary in the face of threats from them? It would just encourage them to continue to threaten to get more concessions. The statements of the other ministers you mentioned were very inappropriate, but it was clear they spoke for themselves and did not undermine the government's position on a critical issue.
The science is becoming clear. The longer a person stays in a position of power the greater the decay in empathy, the less able to accept new information or believe he can be wrong, and the less willing to take responsibility for his actions. Bibi has been in power too long
