I feel betrayed, but it's not a particularly strong feeling for some reason. I expected something like this from Trump, says an anonymous Ukrainian soldier who is fighting in the Kursk region to AP.
Another soldier states to the news agency that the situation looks bleak.
War is very pragmatic. If we have weapons, enough ammunition, infantry, tanks, and planes – top-notch. If not, then we're done for.
Pavlo Kazarin, a journalist and commentator who has joined the army, warns about what will happen without security guarantees.
All those who demand peace from us ignore that the price for peace will then be higher than the price for war, he says.
"Like a knife in the back"
Trump's line is a gift to the Kremlin, according to Ukrainian civilians.
It's like getting a knife in the back. We counted on their support. And we still count on them. It's wrong, in my opinion, says Sofia, 33, in Kyiv.
It's clear that it was a shock. This is our most important ally, she adds.
Continuing to defend Ukraine without US military support will become more difficult, but it's not possible to stop, according to Igor Peresada, 57, in Kyiv.
If we stop shooting, Ukraine will cease to exist as an independent nation. If Putin wants a ceasefire, he can withdraw his forces, and then the war is over.
Unclear what Trump wants
Other Ukrainians say that the outburst has created even more confusion regarding Trump's intentions.
The problem is that it's unclear what Trump wants and what purpose he has with his actions, says parliamentarian Oleksandr Merezjko, who is chairman of the foreign affairs committee.
As it looks now, he seems to be leaning more and more towards Russia and trying to pressure Ukraine to accept Russia's terms. It appears dreadful – to force the weaker side to accept the stronger aggressor's terms, he says to AP.
