Russia and Turkey
I recently read a report in the Kathimerini daily that claimed that since Turkey and Russia both actedlike Imperial states (Ottoman and Soviet respectivley) they would become closer allies in the future. A comment left by anonymous also claimed something to the contrary, but used a different example to support his claim.
I am a proponent of the opposite view, which is, because Russia and Turkey are acting like Imperial states, they are bound to clash. Already, some tension is rising (link) over genocides. Further reasons are the clash between Orthodoxy and Turkey in general (Halki, Moscow as Third Rome, etc). An addition to these sores is Cyprus, which the Mafya uses as a center for money laudering. This too will prevent Russia and Turkey from becoming Imperial chums. Finally, if Russia and Turkey were becoming friendly, then why would Russia choose to build a pipeline through Bulgaria to Alexandropolis instead of negotiating the tariffs with the Turks. Perhaps they realize that their relations with Turkey at the moment might look better than in the past, but the future estimate is shakey.
