You didn't mention the vagueness issue, nor being crushed. And, you're ok with 700 years elapsing?
It's been 2000 years since Jesus came, so another 700 or 7000 years is cool?
It would be better if Isaiah had said He would come in 700 years. Waiting 35 generations until someone comes along that meets most of the prophecy is really not a prophecy.
I can make a prophecy:
He will be born to a middle-class lesbian couple as a test-tube baby 135 years from now. He will stand 6' 4" when He is grown. He will be president of His country at age 26. His IQ will be 192. He will speak six languages and win the Nobel prize in science.
At a political rally for His re-election, He will be killed by an exploding drone operated by his opponent in attendence in a linen closet near the auditorium where He was speaking. No one will ever find out that the opponent killed Him, but the opponent will go on to rule for three six year terms.
His funeral will be attended by about 250,000 mourners, and He will be buried in an eco-friendly casket surrounded on both sides by unmarked graves.
Now, this is very specific. If this prophecy comes true, I would be shocked, frankly. I just made the whole thing up. But, it also gives a time when we should expect Him. Also, this prophecy might be the only thing that gets the opponent who killed Him convicted, perhaps after his third six-year term.
