Israel is just fighting a war now, and they did a lot to avoid it.

That’s just not true, though. Netanyahu’s goal was to intentionally provoke war with Hamas through acts such as West Bank settlement - his government is the most aggressively pro-settlement in recent history - to boost popularity within his far right coalition who reject a two-state solution and want to see Israel annex the West Bank. Netanyahu is being tried for corruption and desperately needs to keep the far right of his coalition on-side to avoid going to prison. By remaining in power, he can attempt to change Israel’s judicial system to stack it in his favour to give himself the best possible chance of avoiding imprisonment.
