London announced Tuesday that it wants to build an "international coalition" to help Ukraine obtain US F-16 fighter jets. Lockheed Martin had also indicated that it was able to quickly supply these aircraft.

Ukraine has been clamouring for months for their high availability and versatility. But to obtain these precious fighter jets, Ukraine will still have to wait for the green light from the White House, which refuses to offer air assets to Kiev for fear of an escalation of the conflict. "Not to cross the Russian border would be to make very limited use of this type of weaponry," says Marc Chassillan.
