European leaders worry they’re too reliant on U.S. tech

The flashpoint seems to come after President Donald Trump sanctioned Karim Khan, the chief prosecutor at the International Criminal Court, over the ICC’s decision to issue arrest warrants for Israel’s Prime Minister Benjamin Netanyahu and former defense minister Yoav Gallant.

Faced with the return of Donald Trump to the Oval Office, Zuckerberg conveniently molted out of his pseudo-progressive skin and into a darling of the manosphere.
