Are you Discojoe's cousin?

LBJ was one of the greatest legislative presidents we've ever had -- e.g. The 1964 Civil Rights Act.

Vietnam unfortunately was an important part of LBJ's failed legacy.

To Trump's credit he is not ignoring the existential threat posed to Japan, the RoK, Australia, and the U.S. by the DPRK, nor is he blind to the PRC aggression in the South China Sea.

But Trump's alienation of Merkel and Macron is undermining U.S. security.  If Trump is not willing to support Article 5, then why should France or Germany or any other NATO country support the U.S. if it gets into a military confrontation with the PRC and/or the DPRK, which is an increasingly likely scenario?

In short, you are correct.  Trump is a boor and his bad manners as well as his myopic strategic vision are hurting U.S. interests, especially with respect to our national defense.
