Conservatives, traditionally, are more isolationist and nationalist in thinking, they are not eager to get involved in all these oversea issues.
Democrats and socialists are all about “workers of the world unite,” a theme that they already had a century ago. They are all about globalism, the UN, WEF...

The problem today is that Republicans are not conservative. They include two large groups that are still big government and/or support international meddling:
1) The modern big government Republicans like Bush/Romney/late McCain... They merely support defense, and their corporate cronies. They pretend to have a moral stance but that's not real since they usually go total secular when it benefits them politically.
2) The devout religious right that thinks their personal moral beliefs should be codified into the law and policies of government agencies. But only their moral idea of right and wrong, because ther guy next to them has it all wrong and his ideas shouldn't be the law.
***Neither of these groups believes in limited government and maximization of liberty (freedom) even though they call themselves “conservatives.”***
I agree - although I think the first group (modern big government Republicans like Bush/Romney/late McCain) is far more influential, as evidenced by their repeated successes in securing the Republican presidential nomination. The second group (devout religious right that thinks their personal moral beliefs should be codified into the law and policies of government agencies), on the other hand, has been shrinking for decades. In fact, the group has fractured, with some large denominations actually supporting the progressive political agenda: apparently their "personal moral beliefs" regarding homosexuality, abortion, open borders, etc. are now more compatible with Democrat (or socialist) "law and policies of government agencies"...
