Liberal/conservative is:
1. Statist
2. Interventionist
3. Collectivist
4. Central planning
More undefined terms but fine , I will tell you what I think they mean, shall I?
Liberal and conservative are diametrical opposites in the context of the United States. Conservatives in the States ( not to be confused with Republicans who are a controlled opposition party) are trying to conserve the original Republic - and are therefore anti-statist, anti-central-planning and anti collectivist , whereas the "liberals" ( not to be confused with classical liberals) are statist (as in the State is the supreme arbiter) , collectivist (as in the community comes before the individual) and pro-central planning ( as in the government "plans" the economy)
The rest of your post was you assigning positions to me that I do not hold. Isolationism is NOT Non-interventionism. The current policy of the USA, supported by liberal/conservatives is Isolationism. We're not even supposed to talk with Russian, Iranians, etc. We're to isolate them via sanctions, embargoes, etc. That is Isolationism in practice....but you call it something else.
Conservatives in the USA march in lockstep with liberals. They are not opposites at all. More like right and left wheels of the same wheelbarrow.
Liberals want deficit spending, massive government, military intervention, and government control over all aspects of life.
Conservatives also want deficit spending, massive government....etc.
The only difference is who is in control, (R) or (D).
Conservatives are also completely detached from reality, much more so than Liberals. Conservatives imagine that a guy like Paul Ryan is a "fiscal hawk," or that Republicans will overturn Roe v Wade, etc. They also have a false belief that conservatives want to shrink government.
There is zero proof for these beliefs, as every republican/conservative politician has increased spending, not overturned Roe v Wade, increased the size and power of government and the like.
Your claim that liberals and conservatives are diametrically opposed is totally detached from reality. There has never been a single instance of any conservative anywhere doing anything remotely conservative, the way you seem to define it.
You choose to deny reality with your labels. I incorporate reality in mine, which is a big difference between us.
I'll not fight for the charade, finance it, applaud it or make excuses. How about you? Are you going to enable the United State to continue down the path to ruin?
