There's nothing to lie about. What we're seeing is a proxy war between the US and Russia. The US explicitly listed conflict with Russia and China as their new strategic focus during the Obama administration. The US was making plans to include Ukraine in NATO under Clinton while Clinton was saying to Russian leaders that this would never happen.

The US has been working on Ukraine for a very long time, as part of the strategy to dominate Europe and keep Russia from competing with them.

NATO, the world's first transnational military force, staffed and led by literal Nazi officers, built specifically to fight Russia, has been deploying nuclear capabilities all around the world to encircle China and Russia. Deploying weapons systems to the Russia/Ukraine border would be a massive strategic check on Russia by the US. The US wanted this. It worked on Ukraine for decades to bring this about.

Russia invaded Ukraine to fight the US. The US funds, arms, trains, recruits, and provides logistical support for Ukraine but the people dying are Ukrainian.

This is the literal definition of a proxy war.
