Kenzo Tribouillard | Afp | Getty ImagesThe dust has barely settled on the decision by the U.S. and Germany to supply battle tanks to Ukraine, but talk has already turned to the possible use of other firepower, namely, fighter jets. Kyiv appears confident that, as with Western tanks, it will eventually be given F-16s too. The U.S. has been tight-lipped about giving Ukraine F-16s, or allowing other countries to re-export their own U.S.-made fighter jets to Ukraine (National Security Council spokesman John Kirby said he had no announcement to make on the issue Wednesday). How helpful fighter jets would be to Ukraine is a matter for debate, and depends on the aircraft, its weaponry and flying conditions, experts note. Germany arrived at its decision to send tanks after months of pressure and deliberation, making any question over fighter jets a very distant prospect, according to Carsten Nickel, deputy director of research at analysis firm Teneo.
