A useful idiot or useful fool is a person who thinks he is fighting for a cause without fully comprehending the consequences of his actions, and who is cynically manipulated by the cause's leaders or by other political players.[

One of the most powerful people in the world is Vladimir Putin.
His aim is to disrupt and de-stabilise the West.
His useful idiots include Nigel Farage who aimed to take the UK out of the EU and Alex Salmond who aimed to take Scotland out of the UK.
Farage and Salmond were both given their own programmes on the Russian state broadcaster Russia Today which has now been banned in the UK. Farage, with the help of other useful idiots like Boris Johnson were successful in achieving Brexit which has been disastrous for the UK.
Fortunately Salmond has not yet been successful in destroying the Union of Scotland and England, Wales and Northern Ireland.
By far the most influential of Putin's puppets (or Putin's useful idiots) is Donald Trump, who Putin got elected as US President in 2016 and is still maneuvering into position to seriously challenge Joe Biden in 2024. If Trump wins the USA is likely to leave NATO and become an authoritarian dictatorship.
Please reach out to any American friends and impress upon them the danger that the USA and the Western world could be in if Trump is re-elected. We must not allow Putin's will to prevail.
