Since Jews hate Christians, how does his relationship with so many Jews make sense?
That premise is too broad: Jews do not generally hate Christians. Judaism and Christianity have important theological differences—most notably, Judaism does not accept Jesus as the Messiah or as divine—but disagreement is not the same as hatred. Jewish views vary widely, like Christian views do.
There is also a painful history of Christian antisemitism and persecution of Jews, including the Holocaust, which understandably affects Jewish-Christian relations. But modern Jewish-Christian dialogue, cooperation, friendships, and political alliances are common.
So Trump’s relationships with Jewish people and Chabad leaders are not contradictory. They can be based on:
shared political interests, especially support for Israel and opposition to antisemitism;
personal and family connections;
Chabad’s outreach to non-Jews and public officials;
mutual respect without sharing the same theology.
His Jewish associates may support him politically or personally while remaining fully Jewish; that does not imply they regard him as Jewish or agree with Christian beliefs.
How much is money involved, I notice you leave out Jewish loans to Trump?
You’re right that money and business interests are part of the story, and I should not have omitted them. But it is important to distinguish Jewish individuals or companies from “Jews” as a group.
The clearest documented financial connection is Deutsche Bank, which is a German bank—not a Jewish lender. It lent Trump’s businesses more than $2.5 billion over several decades; at one point, it held more than $300 million in Trump-related debt. One major loan was $170 million for the Old Post Office hotel in Washington, D.C., and another was $125 million for the Doral golf resort. Deutsche Bank later ended its relationship with Trump’s company.
There were also financial ties involving Jared Kushner, Trump’s Orthodox Jewish son-in-law. A Kushner company received a $285 million Deutsche Bank loan shortly before the 2016 election, and Kushner’s family had other credit arrangements with the bank. But that was a business loan—not a “Jewish loan” in any religious or communal sense.
Trump’s relationships with Jewish donors, businesspeople, and organizations can therefore involve a mixture of:
family ties through Ivanka Trump and Jared Kushner;
political support for Israel;
shared conservative politics;
personal friendships;
donations and fundraising;
ordinary commercial lending and real-estate transactions.
Those facts can raise legitimate questions about conflicts of interest or political influence. They do not, however, support the idea that Jews collectively financed or control Trump, or that his relationships with Jewish people are best explained by a single religious or ethnic motive.
