The "right" isn't just one homogeneous mass with a a single set of beliefs....there's no "alt-right" or "populist" neo-cons.....they're nothing to do with the alt-right and are generally as opposed to them as the left are.....all the NeverTrump Republicans like McCain were/are neo-cons....hell Globalist anti-Nationalist poster boy Macron's a classic centre-right neo-con .....in fact the left are as often the unwitting shills and useful idiots of neo-cons as they are anyone... 
Of course, both the "left" and the "right" aren't homogeneous and what defines each branch varies from country to country. In Asia, both the left and right were/are nationalist as both 'sides' in the 19-20th centuries opposed foreign influence (Japan, China) and colonial rule (Vietnam, India).
Macron is centre-right but he isn't a neo-con. A neo-con rejects the post-1960s social revolution and is socially conservative. Technically, neo-conservatism applies to American politics. Neo-con is used more as a pejorative term elsewhere just like "the use of the word "left". As 65 said it's "words".
...and Britain is not a mess thanks to Brexit, the Conservative Party is...Britain will soon be a mess if that delusional Marxist halfwit Corbyn and his comrades and cohorts of dopey eternal undergraduates win the next election..
Britain is in limbo thanks to Brexit as no one (eg: business) can plan beyond March 29 and the main problems with this current Brexit deal won't be resolved by then (hence this "backstop" idea over the Northern Ireland border). It was an undefined referendum and now the Brits are paying for it. It will also cost another PM her job (even if May wins this leadership spill) so the uncertainty will only continue for longer. It's an utter shambles and it's all self-inflicted!
As an Aussie, I couldn't care less who wins the next UK election. It's not as though Britain is a world power anymore. It's not my homeland either, thank god
. The underlying issues over there won't go away whatever happens. The economic centre of the world is moving to the Asia-Pacific region and away from the Atlantic. Great for us; not good for them.
ps. Got to laugh at the "stability" and "leadership" that their useless monarchy provides too
. More concerned about making the celebrity pages these days
