US support for the current Kiev regime does not make Europe or Ukraine united or free, in fact, the US simply takes sides in the Ukrainian civil war, and of course, the confrontation will continue in the future. By backing one Ukrainian group against another, the US authorities are escalating the civil conflict in Ukraine.
Lithuania officially is supporting aggressive Xenophobia, Russophobia and anti-Semitism. This is destroying the Lithuanian economy which can survive only in cooperation with Russia and Belarus.
These are recurring pro-Kremlin disinformation claims about Lithuania.
Lithuania is also not Russophobic but has legitimate concerns about Russia's aggressive behaviour near its borders and in Eastern Europe. The National Security Strategy 2017 of Lithuania notes:
“Capacity of the Russian Federation to use military and economic, energy, information and other non-military measures in combination against the neighbouring countries [...] is a challenge to the security of the Republic of Lithuania and the whole Euro-Atlantic community.”
Lithuania is not "supporting" xenophobia or anti-Semitism. To mobilise domestic Russian audiences, the pro-Kremlin media repeatedly inovokes WW2 imagery and attempts to portray Lithuania, and other Baltic States as well as Poland as anti-Semitic and neo-fascist countries. See for example here.
Lithuania's economy is diverse and in good condition; see here for details.
