I have no love for modern capitalist Russia, or for Vladimir Putin, but there are always two sides to a conflict. Regrettably, the Guardian gives credence mainly to the anti-Putin version. In that narrative, the Russian leader is alleged to have violated Ukraine’s sovereignty, though no hard evidence is offered. For those who support western Ukraine’s criticism of Putin it is salutary to remember that the present government came to power via a coup. Moreover, many of its supporters are self-confessed followers of Nazi ideology.

For the Guardian, one of Putin’s main transgressions has been the annexation of Crimea. But this is dangerous ground for western critics of Putin, as a moment’s reflection should remind one that Israel routinely annexes Palestinian land but has never been censured for its action. Turkey, which annexed northern Cyprus, has never been subjected to sanctions. Two wrongs do not make a right, but it is morally shaky ground for western leaders to condemn one country for annexation while condoning it by another power.

As David Owen has pointed out (26 August 2014), Russian leaders are understandably worried by the eastward march of Nato, threatening its security. If we wish to avoid catastrophe in Europe the west must come to a diplomatic agreement with Russia, however difficult that may be (Report, 8 February). The alternative is unthinkable.

• The solution to Ukraine has been floated – and ignored – before. Treat Russia as part of continental and cultural Europe. Field a joint EU peacekeeping force with Russia and Ukraine. Fly all three flags. Enforce and police the Minsk agreement. Leave Crimea for another day. Use an EU Marshall plan to rehabilitate eastern Ukraine. Recognise significant regional autonomy within a unified Ukraine. This is something the UK should lead with France and Germany, rather than waiting for Washington to let us do it.

• David Cameron could play no part in the Moscow talks (Report, theguardian.com, 7 January). Britain is a US puppet state, which for decades has not had a foreign policy separate from that of the US. Since America precipitated the Ukraine crisis by orchestrating the coup in Kiev, it would not be appropriate for Britain to play any part in mediation.
