According to his Wikipedia page, he is "the region's pre-eminent spokesman for The Conservative Nation," and a columnist who had "quickly established himself as a must-read." Also according to Wiki, he takes a paycheck from the radical left-wing TV station WBUR, one of the many governments run NPR affiliates in New England. He's also been on the payroll of the Progressive cable outlet CNN.

It's fair to say Jacoby is typical of Official Conservatism™ the last two decades, which is to say he is a neocon. There used to be a time when there was a big enough distinction between Official Conservatism™ and the Trotskyites that migrated from the Left in the 70's, but all of them are neocons now. Jacoby was gonzo for the Bush policy of invading the world – invite the world. He continues to say the Iraq War was a success and he is endlessly going on about the Czar and how Trump is a tool of Russia.

If opposition to the Soviets defined the neocons in the Cold War, opposition to Trump is what defines them now. You see that in this Jeff Jacoby column from the other day. The gist of the piece is to remind the reader of America's past terribleness and then to tie that history of terribleness to the rise of Trump.
