If Putin is really this powerful then why does he really need to try to conquer any nation? He already controls everything and everyone according to liberals.

He's like the liberal Soros. Just has infinite money and influence to pay people off, and they can easily attach blame to him over a political anomaly they don't understand.

Remember liberals actually played the entire "stolen election" meme before Republicans did, after losing to Trump by claiming he illegitimately won by getting help from Putin.
