When Bennett came to power, he never thought his power would just last a year since he and Lapid agreed to be in charge for two years each. This is while Bennet remained the Prime Minister less than a year; more importantly, he decided to leave politics forever.
Now the question is what factors led Bennett to take such a decision.
One reason seems that he surrendered to the destructive measures of former prime minister, Benjamin Netanyahu, the tough competitor, against him.
Despite the fact that Netanyahu gained a majority in Knesset, he could not become prime minister for many reasons including his corruption case in which Bennet was involved. He considered Bennett his protégé and never expected his betrayal.
In response, Netanyahu used every opportunity to strike a blow to the Israeli coalition government to lose the majority. Netanyahu could reach the goal by removing two from Bennett's party and the coalition. He also prevented the approval of the bill on the expansion of the Israeli rules to the Jewish settlements in the West Bank and caused dissatisfaction among Jewish settlers. All caused Bennet to resign.
There is no doubt the depth and breadth of the crisis and the internal gaps in the regime's political body played a role in Bennett's resignation. Perhaps Bennett thought his resignation might ease the crisis.
Another element could be Bennett's tactic in the past year to involve the Israeli regime in cross-border contentions, especially the ones related to Iran and its regional allies. Bennett wanted to leave an acceptable record in the face of his competitors including Netanyahu -who often accused him of being inefficient- by disclosing its invasions against Iran's interest.
However, the strategy caused Israel to be in a defensive position while providing an opportunity for the resistance forces to respond to the Israeli invasion more passionately.
From this point of view, Bennett's resignation is not just a personal decision but a decision by the Israeli authorities to increase the regime's security factor. This is while it seems unlikely the tactic could result in what favors Tel Aviv.
