Is this the Fox News thread?. For your information immigration is a hot topic in Britain now; as well as defence spending, which some political parties are receiving popular backing because of their stances on both. I however won't get drawn into a debate on the ethnic make-up of the UK.
Here's a thought on why the UK is drifting away from the US, look at your anti-British president and his attitude towards the UK as a whole. Try looking at the UK spilling blood in Iraq and Afghanistan only for it to not matter one bit. Maybe the British government and public are tired of following the US line when Obama can't even be bothered to pretend to be neutral on British sovereign territory disputes (or the 'Islas Malvinas' as he called them).
The French are interested in Africa because a large area of it is their old stomping ground, not the UK's, and thus they have a vested interest in protecting countries loyal to France. This coincidentally aligns with US thinking in the region. When they start deploying ground troops to Ukraine, the Baltics, and Iraq then let me know.
One thing for you to all bear in mind as well is the French started the process of deep cuts to its military last year, something Britain started five years ago. So by 2020 they certainly won't be in the same state as they are today and perhaps their global influence will diminish as well.
