“We’re going to talk,” Biden told reporters, speaking the morning after he answered with an emphatic “no” when asked at the White House whether he favored sending F-16 fighter jets to Ukraine.

The United States is by far the biggest supplier of weapons to Ukraine, where the Russian operation is now approaching the one-year mark. A coalition of other Western countries is also sending arms, ranging from rifles to armored vehicles and artillery.

Now, Ukraine is pressuring for fighter jets and long-range missiles that could hit Russian targets far behind the front lines.
