She is correct in saying that China is playing the dotard for a fool.
Based on WHAT, exactly?
Despite frantic fear-mongering screams from the Left about Trump causing a Trade War that will devastate the United States, President Trump has instead gotten them to agree to new trade negotiations without any such Trade War.
Despite the Left's condemnation of Trump for holding talks with North Korea...then condemnation for NOT meeting with them...then condemnation for scheduling to meet with him again...and all the while putting pressure on China that has in turn engaged in diplomatic negotiations with North Korea that has already resulted in historic events - like Kim leaving North Korea and his willingness to meet - the President is closer now to disarming North Korea of its nuclear weapons and of bringing peace / a possible true end to the Korean War than any other President.
North Korea demonstrated its possession of nuclear weapons and acquired ICBM Missiles capable of reaching Americans on Obama's watch, while he was busy financing/arming/training/aiding terrorists and dragging the US into 2 Un-Constitutional wars... Trump has stepped in and already done not only what Obama could/not do but that no other President has done...
...and of course that is note enough for snowflakes and extremists.
