Putin has many flaws, Russia has little democracy, but having weighed up the other option, which is WWIII involving nuclear missiles, I'd rather try and make a deal with Russia and see what we can agree on, such as like together fighting ISIS and the Al-Nusra Front etc and see what other common ground we can agree on, rather than have WWIII and mutually assured destruction (MAD)
There would be no winners of WWIII, there would only be losers, and whoever happened to be left would be left with nothing but dust and horrific disease that they themselves would die from.
Mutual assured destruction - Wikipedia
Russia wants Trump to loosen sanctions so that they can take over Ukraine and the rich oil reserves in the Crimea. The fact that Putin is brazen enough to interfere not only in the US election, but in current European elections, demonstrates what a threat he is to modern democracy.
The best thing we could do with both the UK and Iran is to leave them alone.
If Russia wanted Ukraine they would have taken Ukraine by now, this situation has been ongoing for two years, this suggests that Russia has no interest in taking Ukraine and why would they? The Ukraine is a bankrupt nation now financially in debt to the IMF who had to give them a massive loan due to them having no money anymore.
Russia also didn't "annex" The Crimea, annex means you take some patch of land against the peoples' wishes, the Crimeans had a referendum
When the CIA organised coup happened, the first thing Washington DC's Puppet Rulers in Kiev did was outlaw anything Russian in The Crimea and as most of Crimeans are Ethnic Russian they rightly freaked and decided to have a referendum, the question being did they want to return to Russia or did they want to stay with The Ukraine and they voted that they wanted to return to Russia.
Also the Russian Black Fleet founded by Prince Grigory Potemkin has been based in The Crimea since 1783 and this has been crucial throughout history to the defence of Russia.
The Crimea was Russian from 1783, until the Bolsheviks came along and made it an autonomous republic and then later it was declared The Crimean Oblast and then in 1954 the Ukranian Nikita Khruschev gave The Crimea to The Ukraine.
In Crimea, 65% are Russian, 15% are Ukranian and 12% are Crimean Tatars, so it was natural that they'd vote in their Referendum to rejoin Russia post-Maidan.
Post-Maidan Ukraine, is it any wonder that the majority of Crimea voted to rejoin Russia when they ARE Russian and NOT Ukranian.
Also, in the Ukraine Parliamentary election of 2014, essentially something straight from a Banana Republic, a huge portion of Eastern Ukraine wasn't allowed to even vote, this disenfranchised more than 3 MILLION people from the voting process, this not allowing them to vote was blamed on the War in Donbass.
