President Donald Trump’s persistent critique of Germany’s lack of defense spending seems to have motivated one of Europe’s wealthiest countries to make a move.

Trump’s disapproval of Berlin has driven Germany to boost investment in its military forces and infrastructure, areas that have faced substantial criticism for their poor condition.

Richard Grenell, who served as the U.S. Ambassador to Germany during Trump’s initial term, mentioned to Fox News Digital that “numerous German leaders disregarded President Trump’s cautions that Russia was weaponizing energy against them.”

the Bundeswehr University Munich, said of Germany and Western Europe’s failure over the decades to address its severe defense deficits, “Now we get the receipt for everything we neglected.”

Fox News Digital sent a detailed press query to the German Foreign Ministry about Trump’s criticism that Berlin has chronically underinvested in defense and remained wedded to Putin’s gas supply after his warnings.
