Because the Ukrainians are doing a great job and don't need us to fight for them.
The former vice president is "convinced" that if Ukraine doesn’t repel Russia, "it’s not going to be too long" before Russia forces NATO to get involved.
It's time to acknowledge objective reality and employ policies that can work. There is no realistic basis to believe that Ukraine has the capacity to attain its stated strategic objective to reclaim all its territory, including Crimea.
Washington has spent nearly $113 billion over the course of this war, provided Ukraine with an astounding volume of modern arms and ammunition, and delivered an impressive array of training and intelligence support. But after almost a year of preparation, Ukraine has hardly dented the Russian lines.
Although Ukraine appears to have finally penetrated the first line of Russia's main defense, the most difficult part of Russia's defensive system has yet to be overcome: the hundreds of kilometers of dragon's teeth, tank ditches, and yet more vast minefields. The best Ukraine can likely do for the rest of the year is to hold what they have and prevent the possibility of losing more territory to a potential Russian counteroffensive this fall.
