Unfortunately your question gives JWs a "get out", that doesn't reflect reality.
JWs (like gmlow) will argue that every knee will bow to both Jehovah and Jesus and that since Jesus submits to God He isn't God. In other words, focusing on knee bowing doesn't mean Jesus is God.
However, had you quoted the whole verse there is a different point that JWs cannot so easily escape!
"...that at the NAME of Jesus every knee should bow, in heaven and on earth and under the earth,"
In other words it's to the NAME of Jesus ALL shall bow. Hmmmm but wait what about....
"..Wherefore God also hath highly exalted him, and given him a name which is above every name:" In other words Jesus name is ABOVE ALL NAMES.... ALL.... but of course, the NWT don't like this and has to include the word "other" to show that Jesus name cannot be above the Fathers..
Even if we accept, and we cetainly don't, that JWs are right about this being any "other" name they have a problem because if Jesus name is only second highest name, is the name by which we all saved, is the name to which EVERY knee will bow, why is it the highest name is not known throughout the world as well, as widely,etc ?
ONLY IDIOTS would argue that Jehovah is a name with more glorify and avoid the fact that God tells us "And My glory will I not give to another". but more than this ... JWs actually admit that Jehovah isn't God's name anyway!
"Yahweh . .. is admittedly superior to Jehovah. 'The wrong spelling Jehovah OCCURS since about 1100' and then it offers its arguments in favor of Yahweh as the correct and original pronunciation." Let Your Name Be Sanctified, Jehovah's Witnesses, p 16-20)
"While inclining to view the pronunciation "Yahweh" as the more correct way, we have retained the form "Jehovah" because of people's familiarity with it Since the 14th century. New World Translation, Jehovah's Witnesses, foreword p 25)
Could they be anymore confused?
Isn't their mental double back flips with three twist cognitive dissonace impressive?
