"Is PM Netanyahu's upcoming election prompting his supporters to this extreme behavior?"

ZIONISM is prompting this extreme behavior. This has never been about Nuttyyahoo. He is only a singular manifestation of the sickening underlying disease of ethnosupremacist fascism.

The evidence is obvious and it is mounting. Israeli Zionists and their supporters are the number one enemy of future America.

You spelled "Israeli Terrorists" wrong.

They were terrorists in the 1920s
They were terrorists in the 1930s
They were terrorists in the 1940s
They were terrorists in the 1950s
They were terrorists in the 1960s
They were terrorists in the 1970s
They were terrorists in the 1980s
They were terrorists in the 1990s
They were terrorists in the 2000s
They were terrorists in the 2010s
And they are terrorists today.

They will always be terrorists. Because their ideology demands that they be terrorists.

In order to remove the terrorists, you need to eliminate the ideology. Unfortunately, as long as humans roam this planet, there will be tendencies toward ethno-supremacist fascism, so you seek to minimize and isolate the ideology.

You don't do that by giving extended standing ovations to their leadership when they visit. To do so simply invites normalization and propagation of the ideology stateside. Thank both the Republicans and Democrats for that.

Always remember that MAGA is simply Zionism (supremacist fascism) in disguise. Zionism and MAGA both seek to "bring back" a fantasy-- an idealized vision of a time and society that once were deemed "great". One looks back 80 years while the other looks back 3000 years. They use their holy books as a superficial prop to manipulate the religious plebes to accept their barely-hidden nihilistic cult leanings.
Both groups are militant, expansionist, well-financed bully states that use terrorism and mass surveillance to control dissent. They are actively focused on promoting chauvinism and eliminating empathy in order to create a permanent second tier of oppressed, second class citizens.

To them, "Amelek" = "Liberals" and vice-versa.

And YOU are AMELEK.
