US National Security Adviser John Bolton will be visiting Moscow in the coming week to try and lay groundwork for a meeting between President Trump and Vladimir Putin next month. Trump will be in Europe then for a NATO summit in Brussels, and then a state visit to Great Britain. The proposed mini-summit of sorts between the two leaders is the latest attempt by the White House to build a friendlier relationship with Russia. Earlier this month at the G7 Summit in Quebec, Trump tried unsuccessfully to convince the other members to readmit Russia, which was suspended in 2014 following its annexation of Crimea. Relations between the US and Russia have been cold for quite some time, though there has been a large amount of backchannel discussion between the two nations over security concerns, namely Syria.
It is worth noting that there are no plans to include European leadership in a potential July talks. The exclusion of EU members, and NATO allies sends a blunt message to Europe about the reemergence of US leadership on the global stage, and the current state of relations between the United States and Europe. The Trump administration does not intend to be encumbered by European actions and interests, or be bound by a lack of consensus among its European allies. Right now, Washington and Europe have significant disagreements on a host of issues including security, trade, and immigration. There’s little chance an overall agreement could be reached right now on how to approach Russia.
Therefore, the United States sees fit to take the lead.
