All you do is is deliberately misconstrue posts, when you do that then you are admitting to me you are wrong.
Of course Putin can lie, but there has to be a beneficial consequence of a lie, if he were to say he's willing to leave Ukraine on the basis of Ukraine not joining NATO, how would a lie benefit him? He either leaves Ukraine or he doesn't, the situation either improves or stays the same. How would Putin benefit from lying? Or are you saying he'd take the entire Russian army out of Ukraine only to attack again and have to retake all the land? What you're saying makes zero sense, did you think it through?
