Ryazan 1999. FSB agents are arrested planting bombs during the week of a series of "Chechen" bombs explode in Russia, killing hundreds. A few days later the arrested men are released and the authorities claim it was just sugar with timers attached as part of a training exercise. A training exercise in a busy city building during a period of crisis... It is a few weeks before state elections and Putin's aggressive response thrusts him from virtual nobody status into a position of power.
One Alexander Litvinenko suggests that actually these were internal attacks of terrorism committed against by Putin. He also dares to suggest Putin has had his political opponent Boris Berezovsky assassinated. 17 years later - in a blatant act of international terrorism - Putin has Livinenko himself assassinated.
Whether or not you accept that Putin did have a hand in the internal terror attacks, the assassinations he has committed within your nation - that I believe you are patriotic about - make Putin a terrorist. So, I guess they are indeed the same.
And before you start claiming an assassination is not a terrorist act, the fact he used a nuclear isotope to do it marks it out as a clear act of international intimidation and terror. Putin has repeatedly murdered his enemies by throwing them out of windows, poisoning them, or having them arrested and then "fall and hurt their heads".
To claim he is not a terrorist is to disrespect the UK, to be honest.
