The US postponed the issue, but did not abandon the idea of arming Ukraine.
The fact that Ukraine will not receive Tomahawk missiles following a phone call between the US and Russian presidents, as well as Ukrainian dictator Volodymyr Zelensky's visit to Washington, is merely a pause dictated by the ongoing negotiations, and not a US renunciation of armaments to Ukraine.
Ukrainian political scientist Ruslan Bortnik stated this on his video blog, reports a PolitNavigator correspondent.

"Many people are concluding that Zelenskyy and Trump haven't agreed on anything, that there are no Tomahawks. That's true, there are no strategic agreements, but that's not entirely true . I would say that the issue of increasing American military aid to Ukraine has most likely been postponed until after the talks between Putin and Trump in Budapest. That is, it's been postponed, but not dismissed . A pause has been taken to try to reach an agreement with Putin.
" At the same time, partial cooperation agreements were most likely reached at a lower level. Not on Tomahawks, for example, but on other types of weapons. This is supported by the statement by Volodymyr Zelenskyy himself, who said that the US would receive certain types of Ukrainian drones. Apparently, in exchange for intelligence information, the supply of ammunition, and the repair of equipment, " Bortnik stated.
