Sen. Von Hollen and Toomey are two of the weakest senators in Congress. Von Hollen (D-MD) is a typical mouthy quish and Toomey (R-Pa) is just as sleazy/quishy.
Both know that any sanctions against Red Chinese individuals are useless, like trying to stop a hurricane with a fart.
Good way to weasel around confronting Red China head-on about their violations of human rights, political agreements, territorial provocations/aggression, and war-posturing against smaller, non-nuclear armed nations.
In other words, these two are cowardly senatorial turds. They make a lot of stink but do nothing other than make a little noise and then dry up like all dog crap does.
If China is willing to go to war (probable) and we are not (certain) then they are in control of events.
