It’s like they’ve convincied themselves that they’re invincible.

Makes sense to me.

The US is actively covering for their genocide at the UN and arming them to conduct it.

They have nuclear weapons and have blackmailed the entire region plus insinuated in threats that they would nuke western cities if their occupation fell in retaliation.

They are strategically important to the US and have been a bipartisan agreement for decades. The US plans to use Taiwan in a war against China in the near future, if they abandon important partners like the zionists their pawns in Taiwan may notice and resist being used that way.

Biden is a known zionist. Trump will also support them they believe and not without cause.

They have a huge, powerful lobby and the anti-semitism card which has given them dominance of the western and in a real way global media.

Facebook is viciously censoring and suppressing the truth about the genocide of Palestinians by the zionists as well as any criticism.

Most gulf states are run by those in the US orbit and wouldn't dare to do anything to help.

All of it adds up to the fact that they have a reason to think this way, many reasons.
