The White House plans to pay for the additional weapons and equipment with a budget request of more than $3.4 billion for military spending in Europe in 2017, several officials said Monday, more than quadrupling the current budget of $789 million. The weapons and equipment will be used by American and NATO forces, ensuring that the alliance can maintain a full armored combat brigade in the region at all times, The New York Times wrote.

Administration officials said the additional NATO forces were calculated to send a signal to Russian President Vladimir Putin that the West remained deeply suspicious of his motives in the region.

As UNIAN reported earlier, on November 25, 2015, U.S. President Barack Obama signed into law S. 1356, the revised National Defense Authorization Act for Fiscal Year 2016, which authorized, among other things, $300 million assistance for Ukraine.
