Although TLS Guy is an old British-style Tory, and I'm an old US-style Democrat, we share the same views on Russia. Russia is a threat to all western nations, and some nations in the east as well.
Russia, under a wide variety of different governments, has always had the same foreign policy goals – invade & dominate others before they invade & dominate you. This has certainly been true whether under Putin (a former career KGB officer during the Soviet Union days), Lenin, Stalin, Khrushchev, etc. in the Soviet Union, or the various Tzars, Nicholas, Alexander et al. of the Imperial Russia days. Their major weapons are murder, espionage, blackmail, extortion, and false propaganda. These are more effective during peace time than during war.
The best peace time weapons the USA and others have are the frequent and loud repetition of the truth by a free press, plus maintaining an aggressive military presence. Believe it or not, the Russians are not only sensitive to outside criticism, they are also extremely paranoid. These tactics worked against the Soviet Union during the very long Cold War. Unfortunately it requires an expensive, full-time commitment.
The present US president's wishes to retreat from a strong world-wide diplomatic & military presence is an open invitation to Russia to step in and cheaply accomplish it's goals.
