How would NATO deliver F-16s and where exactly would they be based? Neighboring Poland and Romania both operate these jets and already have the necessary infrastructure, making them the likeliest candidates for stopgap basing. In addition, Slovakia and Bulgaria are in the process of acquiring F-16s and are rapidly building similar infrastructure, meaning they too are able to do the same or at least they will be soon. However, will Russia really tolerate this, considering that F-16s using NATO airbases would make them a party to the conflict?
