There are people on RE that think Israel does what it does because of Donald Trump emboldening them to do something they've been doing for 70 years.
This theory is not that 'crazy' to be honest.
Obama wasn't very fond of the Israeli government and didn't get along well with Netanyahu at all.
He didn't like Bibi trying to torpedo the Iran deal behind his back for starters. Of course the US would never outright drop support for Israel but there was always the risk that if Israel took it too far the US would limit its support or stop vetoing UN resolutions against Israel. The US is paying for and responsible for a big share of Israel's security either directly or indirectly and without the political and military aid the state would likely not last very long. At least not in its current form.
Just like Saudi Arabia can turn its border with Qatar into a literal nuclear wasteland because Kushner likes the prince there's nothing that Israel isn't permitted to do by the Trump administration after the Ivanka embassy stunt:
So although it might not embolden them, the current political situation sure ain't restraining them either.
