Blinken gives Poland "green light" to send fighter jets to Ukraine reports the Epock Times:  https://www.theepochtimes.com/us-gives-poland-green-light-to-send-fighter-jets-to-ukraine-secretary-of-state_4320874.html?utm_source=News&utm_campaign=breaking-2022-03-07-1&utm_medium=email&est=YGc0ZhWBFdC307vHxiOBdvpcopM4Id0bNjlJjcn9b8LAXA4F2sjm3A%3D%3D

The number 17,000 seems fantastic.  It is substantially larger than the entirety of the Russian tank force, reportedly 12,400, few of which are in Ukraine.  Whereas weapons could enter Ukraine from Poland and Romania which border the western part of Ukraine, how would they get to the surrounded Ukrainian forces?  Moreover, as Poland and Romania are already on Russia's potential target list because the countries host US missile bases, why would Poland and Romania want to cross a red line by getting involved in the conflict?
