Each country can take sovereign decisions to hand aircraft to Ukraine - White House

The White House Strategic Communications Coordinator for National Security and Defense John Kirby said this at the briefing. 

“These are all sovereign decisions.  And if a NATO nation or even a non-NATO nation wants to provide capabilities like fighter aircraft to Ukraine, that’s certainly their decision to make,” Kirby states.

For example, the White House spokesman commented on the UK's statements about its readiness to train Ukrainian pilots in NATO-standard fighter jets. He argued that the provision of any sophisticated military equipment involves multi-level training:

“We’re doing it right now.  Fort Sill, Oklahoma, we’ve got Ukrainian soldiers learning how to use a Patriot battery. And outside of Ukraine, we’re helping train them on combined arms maneuver, ” John Kirby said.

• On February 10, the Netherlands confirmed that Ukraine had requested the delivery of F-16 fighter jets.

• On February 9, Polish Prime Minister Mateusz Morawiecki said that his country was ready to provide Ukraine with modern fighter jets, but first it should be done by those NATO member countries that have more of them.

• At the end of January, former Pentagon chief Mark Esper called on the United States to provide Ukraine with fighter jets and long-range missiles as soon as possible.

• Ambassador to the United Kingdom Vadym Prystaiko said that Ukrainian pilots are already being trained to fly Western fighters, which will be delivered in the near future.
