Choose an opponent's died and force them to resolve it, if able. The if able as I understand it means that if they pick a for that cannot be resolved that it simply has no effect. Thoughts

Yup. That's right. The card can't force you to resolve a die that can't be resolved.

The real usefulness of this card is that you can either make them leave modifier dice stranded or force them to waste a resource on a bad dice side (like the 1 ranged damage side on an E-WEB emplacement when they don't control the battlefield.)

Seems like a solid way to deal with a force throw special before you roll in as it will force them to remove another of their dice as well.

sure you might still take a little damage but it means your less likely to have a high value die of your own thrown at one of your characters

You can use the Force Throw on itself. Still lose the Force Throw die, but avoids losing anything else.

Can't you make them force throw their own dice

Yeah, if you force them to resolve Force Throw they must remove the Force Throw dice and one other dice. You can't use the Force throw on itself, because the dice has to already be out of your pool for you to be resolving it. If you have no dice in your pool, they have to either use Force Throw to throw one of their other dice at you (maybe throw a dice that has a resource cost or one that's showing shields or some other thing less useful than damage) or throw a blank at you, doing zero damage. Either way, you're taking two dice out of their pool.

This isn't correct.

RR, page 14: To resolve a die, a player must pay any costs and carry out the effect represented by the symbol on that die. Then they return it to the card that it came from.

You don't remove the die from the pool until after the effects have fully resolved. There's no limbo state for the dice - they stay in your pool while you're resolving it. This is why Vibroknife's ability works for its own die.

Alright. Looks like I slightly misspoke when I said it's already out of your pool. It's not already out of your pool, but it still has to be there after it's resolved, hence the rules say "then they return to the card that it [sic.] came from" not "then, if possible, they return to the cards they came from."

I'm pretty sure the Force Throw dice has to be used to remove a different dice that you aren't currently resolving. You can't finish the step of resolving a dice if it's no longer in your pool. Think about it this way: if I have Darth Vader with a Force Throw and I play All In, can I use Force Throw on Darth's dice showing 3 melee damage and then resolve the same 3 melee dice again, for a total of 6 damage? Technically, it's all part of the same "resolve" action... Therefore, unless the Force Throw/All In combo just stated is legal, I don't think Force Throw throwing itself is legal either.

Also, the reason Vibroknife works on itself is because it specifically says so on the card. If that were an inherent game rule that applies to other cards, they wouldn't need to put that rule on there.

No, because you remove the dice from the pool after you resolve the die, not after you finish the entire action. Otherwise, the original rules would have let you just infinitely resolve any single die (before they added the "once per action" limit). You can resolve multiple dice during an action, but each of those resolutions is independent.

Again, no. The text which says Vibroknife affects its own is italic, and the rules say:

The italicized text that explains keywords on cards is solely reminder text, and is overridden by the full rules written below.

(If you'll pardon me italicizing the line about italics).

If it's in italics, it's just a reminder or clarification, not truly a part of the ability.

It's definitely weird, and certainly something they may decide you can't do, but as of now this is how it works.

(Edit: Meant to go back to this part)

Pretty much everything in Destiny is "if possible" unless stated otherwise. Nothing says the die can't leave your pool before you finish resolving it.
