To that end I would tell Donald to promise countries like Ukraine, for example, would not be allowed to join either the EU or NATO but would be allowed to form bilateral trade agreements with western countries that would allow Ukraine to prosper in return for Russia not interfering in Ukrainian political affairs.
Trump, the US, cannot forbid a country to join the EU. After the Nato turned Ukraine into a bankrupt hell hole where praising of jew-murdering nazi gangs is obligatory, the EU´s interest in Ukraine has dwindled sharply, anyway. The right step are elections in Ukraine with the Party of Regions and Yanukovich allowed to run.
TI would further suggest that the US would strongly support Russia keeping its bases in Syria under long term leases if Russia would drop its objections to Assad stepping down in an orderly way to allow a new government or governments to take control.
What is that American desire to remove President Assad about? Do you have any reason to condemn this socialist but libertarian, secular, progressive and strong government, which is democratically legitimated?
These are things Trump might be able to do but which Clinton would not be able to do because of the history of the Clinton administrations dealing with Russia.
Clinton has no interest in America. The ruling elite already dropped America. Clinton will try to drag the US deeper into the conflicts for reasons that are obscure and make no sense at all.
