Let's not be nieve, of course trade and diplomacy are linked. It is only a question of how strongly, hopefully, not too strongly. Chuck Schumer's comments are idiotic. Yes this problem has been around a long time which means it could have been addressed when Barack Obama was President and it could have been addressed when the Democrats had the presidency and the Senate. His position is also hypocritical. Usually they are complaining about Trump acting precipitously, which he does, but now it's he is acting too slowly after the Democrats had 8 years to do something. More büllshït politics.
