Trump has more in common with fascist Putin than with most European leaders, including Theresa May.
He is an aberration and the next President will probably revert to type, but he runs US policy to help his own business empire
However, over the last several presidencies, US interests have developed more in Latin America, the Middle & Far East, China
European countries need to acknowledge this, get together and organise their own defence
Or accept the price of having to support US wars in these other countries with our own soldiers.
Remember the fury when other European countries refused to join the invasion of Iraq - they were right about no WMDs.
So many British lives (& Iraqi ones) wasted pointlessly.
The US will feel ever more entitled and demand ever more, to keep its troops in Europe
Once the communist USSR collapsed, the US reason for "defending Europe" went with it - and also the main reason we needed protection.
The Russian economy was looted by plutocrats in the 1990s and has been run by Putin's kleptocracy ever since.
It is not remotely the military threat of the old USSR (hence why Russia now fights its battles on the internet, much cheaper)
Russian defence spending in 2017 was $61bn, 20% lower than in 2017
- at nearly $14 billion, this was the largest absolute decrease of any country in the world.
This is despite all Putin’s military bluster, because he & his oligarch chums continue to loot & worsen Russia’s wrecked economy
(which is now about the size of the economy of the far smaller Hungary, which is far from rich)
In contrast, the 29 NATO members spent $900 billion, which is 52% of the world total defence spend
Of this, the US spends $610 billion, although the vast majority is now not in Europe, but for the US interests in the RoW.

The UK, France Germany and Italy spend in total $163bn.
The other European countries would add to this
Currently Russia could mobilise an armoured force of at most 150k personnnel to modern standards.
To carry out a successful attack, an army needs an absolute minimum of 3:1 force advantage, ideally 5:1
So at best they could successfully overcome a 50k force
Instead, the UK, France, Germany and Italy can mobilise nearly 250k with better capabilities, training and logistics.
