It's not to do with "Liberation" from Biden in particular tho, is it.
It's a whole ideology of
firstly where the USA stand in relationship to the world, that is, a change from co-operation, membership of organisations like WHO, concerns for the climate, concerns for developing/poor countries, willingness to take refugees
and secondly an ideology that follows far right doctrine on social and welfare concerns, "small" government (whatever the consequences) and willing to overturn democracy to do so. ie elements of Project 25 and trying to manipulate Europe to the right.
Supporters of this doctrine are always going to put forward or back pro-Trump arguments including in this case on tariffs whether they are logical or not. It's a whole package. "Liberation" means, in the context of ideology, far more than trade relations.
