Someone else pointed this out, and it seems weird that I didn't notice it -
The big picture here may be to put all the pieces in place for war. Strategically forces have already been moved to the Russian border, THAAD (specifically their long range X-band radar systems) systems are being put in place in strategic locations to be able to monitor Chinese and Russian military movements and the US
looks to be cooking up justifications for further 'measures' against their 'enemies'.
Brexit and the political turbulence following has put May in charge and a protracted media campaign to ruin Corbyn means she'll face little resistance in the snap elections. She's the establishment choice, in lockstep with the US. The establishment knows that Brexit will make much less difference to markets than is being sold in the media and have bigger things in mind.
Marcon apparently won with only 24% of the vote, and even that's questionable - I've seen several videos of people tampering with the voting process (people taking the forms for Le Pen so she couldn't be voted for at some polling booths, damaging ballots so that they won't be counted etc.). Again, he's the establishment choice - he can be relied on to follow the US' foreign policy, keep the EU from being forced to change in any meaningful way and generally follow the status quo in relation to immigration.
That leaves Germany. At the moment I'd probably characterise Merkel as following the US cautiously - she's more or less doing as she's told, but still trying to remain 'untainted' in the eyes of voters... Germany's given limited military support to the invasions of Libya and Syria; given their economy and military capacity they could take a leading role but choose not to. The leaked phone calls of Victoria 'Fuck the EU' Nuland relate directly to the EU (specifically Germany) and it's unwillingess to take direct action to depose the Ukraine government.
German elections are in September, so we can probably expect a tipping point sometime before or around then. The election will be between Merkel's party and the SPD, specifically Martin Schulz, who is markedly more anti-Russian. It's outcome will probably be determined by whether the powers that be can 'convince' Merkel to fall in line before that.
I'll expand and post this in a new thread sometime
