4meAndyou Well, I don't take sides in your febrile party-politics, but once I managed to find a reasonably neutral description of what "globalism" actually means, it occurred to me that the opposite is isolationism. No man is an island, it is said, but neither is a nation in any but a literal geographical form.
The USA, like the UK, is a member of or signatory to, a vast range of international bodies, treaties and agreements; many of them issuing what the EU would call "Directives" for translating into each nation's own legal system. I saw a list of the UK set and it was more than ninety! I imagine the same is so for the USA. E.g. NATO, UN and its component bodies, ISO, ones controlling international trade and travel..... That's before any international commercial firms, and many of those are American!
There were shortages of oil but not as a direct result of the attack on the pipeline.
ISIS is indeed active in Afghanistan but is not actually welcome there. It is a bitter rival of the Taliban, which it thinks not sufficiently hard-line, and has carried out a number of attacks in the country. I don't know the two factions' sects but the divisions between Sunni and Shi'a can be very deep and bitter. The Taliban also has its Pakistani "branch" but it is ISIS that is "exporting" itself across as many countries as it can.
Not sure what is the status of opium and heroin there, are now: I think the previous Taliban regime was trying to stop it, but it would need give the farmers practical alternatives.

I can hazard a guess at China's strategic plans. That part of Tibet also borders Pakistan and (from memory) Tajikistan, and China has a long-term international trade and influence scheme called its "Belt Road Initiative". This does involve physical links, such as a new railway across Mongolia into Russia, and buying the Greek port of Piraeus (making that effectively Chinese territory in Greece?). So they might be looking to build border crossings in this very remote area; and they have even talked of building a railway from Tibet to Nepal - presumably through the highest part of the Himalayas, not via another nation.
