Quite the opposite. Part of the reason Trump wanted to end the Russia-Ukraine war so bad was because they wanted to gear up for the "big fight". Ukraine simply wasn't a big strategic priority which is why they wanted to either end the war (best case), or shift responsibility over to Europe if that failed.
Lookup Elbridge Colby - served in first Trump admin and now Undersecretary of Defense. Along with Hegseth and JD Vance, they are all that same line of thought
I don't think the views of all the "high level strategist" types align precisely. But there are very few true isolationists like Rand Paul in the executive branch
I find it doubtful that the current admin would just let China walk in to Taiwan. Trump doesn't want a war, but he's not going to want to get bent over and make the US look weak either.
And its not all that different from Democratic position, its a bit of "Washington Consensus" type of situation, like anti-Communism was during the Cold War. The approach between admins is slightly different however, and the Trump admin doesn't like Europe all that much.
