First, Zelensky as his nation's dictator has never been in combat; although he has pulled on a uniform several times just to pose and mug for the cameras.
Second, bone spurs and asthma, smoking too many doobies, or just outright running away (Trump, Biden, Obama, Bill Clinton) does not seem to have much to do with whether or not one can lead a nation. Trump is good at it. Clinton was okay. Obama and Biden reeked.
Three, just making stuff up about Trump doesn't even fool the average Dem Party voter any more . . . NOT after four years of the nation suffering under Dementia Joe Biden and his handlers.
