Is there one location where they are bound?

Or possibly in four different locations along the Euphrates?

Revelation 9:14 Saying to the sixth angel which had the trumpet, Loose the four angels which are bound in the great river Euphrates.

Close to 40% of the Euphrates flows through Turkey, close to 25% through Syria, close 35% through Iraq, and a small %, merged with the Tigris, flowing as the Shatt Al-Arab river.

The Shatt Al-Arab river is the Iran's most southwest border with Iraq.

Part of the delta of the Shatt Al-Arab river, is Bubiyan Island belonging to Kuwait, where Iranian missiles reportedly struck, on the 27th.

Could one angel be bound in the part in Turkey, another in Syria, another in Iraq, and the fourth in that small part that borders Iran, as the Shatt Al-Arab?

Or are all four bound in the same location? At the head, at the end, or somewhere in the middle?

Is there any possibility that one of the angels could be the prince of Persia, that may have been bound by the prince of Greece, when Alexander the great defeated Persia?

Then could another be the angelic prince that was over Babylon, until possibly bound, when the Medes & Persians defeated Babylon?

If Meshech and Tubal were in what is today, Turkey, could another angel be the chief prince, Gog, possibly bound since the Assyrian king, Tiglath-pileser I, defeated Meshech & Tubal?

Ezekiel 38:3 And say, Thus saith the Lord GOD; Behold, I am against thee, O Gog, the chief prince of Meshech and Tubal:

If this is so, then who might the fourth angel be?
