Putin said that the "green men" without insignia on their uniforms who took over government facilities in Crimea in 2015 are not Russians, until he admitted months later that they actually are. Days before the Russian invasion of Ukraine, Putin reiterated many times that he will not invade and that the Russian troops in separatist-occupied Donbas and Luhansk regions are only there for "peacekeeping". He told the outside world that they are being paranoid over the potential Russian invasion.

Putin and Kremlin lied many times. I don't know why you would still believe someone who has been proven to lie many times unless you have a battered partner syndrome.
