That may be true. The increased deficit is probably due to the fact that the US can still afford to order from overseas during the pandemic, while overseas can't afford squat.
But I still think tariffs need to be across the board and not just on China. Though I think additional punitive tariffs on China are also appropriate.
Overseas can afford to order stuff from the US - but we’re not actually *making* anything they want with most of our factories shut down due to COVID-19 orders. You can’t export what you didn’t actually make.
Tariffs across the board punishes trade partners that don’t take unfair advantage of us; in this case all it does is drive the cost of goods up when they are things we don’t/can’t make here and accelerate inflation. There are a surprising number of things that the typical consumer buys that have no US made option as US production of them have been de facto or actually banned.
Punitive tariffs on people who do cheat, like China, are fair game.
