For Netanyahu it was pay-back time to the Democratic Party for the Iranian Nuclear deal, but for Barack Obama specifically. The Obama administration tampered, albeit indirectly, with the Israeli GE of 2015 through the V15-fund.

Most damage to the Democratic campaign of 2016 was done by joint effort of Zuckerberg's Facebook and Cambridge Analytica (parent SCL Group in the UK). The covert actions by Robert Mercer and Paul Singer were quite effective.

Israeli allies in this effort to get any Republican candidate elected were Saudi Arabia and Abu Dhabi, the anti-Iran coalition. See role played by Erik Prince [DeVos link] and most likely jointly Israeli/Saudi intelligence from the government or in privatized corporations. The quid-pro-quo in favor of these actors was swift and lasting: thanking Trump, Kushner and Friedman.

Just as Hillary would have, so has Joe Biden already bowed to the interests of the Jewish State of Israel. You were right.
