Jack-of-all-trades Jared Kushner flies to the middleast to negotiate peace. Isn't that the job of the Secretary of State?

What diplomatic credentials/experience does Jared Kushner have? Is being Jewish enough if your FIL is the prez, his daughter is your wife and you got her to convert to your faith as well as agree to raise your children in that same faith? Is he a heavyweight/lightweight/weightless?
