The Republicans in the House, as well as the White House Lawyers have repeatedly stated that Ukraine received lethal aid under Trump, but not under Obama. While this is true on its face, they left out an important detail. While Ukraine has received the Javelin missiles, under the rules of the sale, the Javelin missiles have to be stored in western Ukraine, which is far from the frontlines of the ongoing conflict in the eastern part of the country (the Donbas region) against pro-Russia separatists.
In short, the Javelins were essentially provided to Ukraine under the condition that they not be used in the conflict zone.
Accordingly, the Javelins have yet to be used in the fighting, though US personnel are training some Ukrainian forces how to use them against tanks.
Experts on the region have also repeatedly said that Ukrainian soldiers are more appreciative and in greater need of nonlethal aid.
