Why is this remotely relevant ?
Macron and Merkel are the increasingly unpopular leaders of the two dominant members of a failing club that some would like us to remain allied to. Several member states have sensed the growing weakness in the old order and are openly defying the previously unchallenged central control post. This will encourage further acts of defiance leading to irreparable damage to the EU. The Eurocrats were previously warned of the explosion of euroscepticism throughout the EU but foolishly pushed on with their fatal plans for further intergration that the public dislike so much.
The massive failure of these two former titans in their respective near neighbouring countries has everything to do with the UK and Brexit. If their own people are totally unconvinced by them why should we be? Merkel was ruined by her immigration policies and the Marcron boy by his arrogant pursuit of a federal EU controlled by Germany and France.
What has not been considered is that any deal must also go through the EU Parliament. I do not think they would block it but I know they are highly miffed about being sidelined by the EU Commission throughout all of this.
