The iron legs on the statue in Nebuchadnezzar's vision in Daniel 2 were the Roman Empire which split into the Western leg that now contains the European Union nations where the Muslims of the Islam faith have migrated to, and into the Eastern leg where a lot of the Islamic people live although there are Christians living there too.  I believe that the feet and toes part of clay and part of iron are the present day countries living in those areas of the old Western & Eastern Roman Empires which contain both Christians, and Islamic Muslims.  The statue from head to toes represents idolatry.  The idolatry that is present when the Lord Jesus Christ returns will be those worshipping the image of the beast that He will end upon His return which is shown by the Stone smiting the feet of the statue to set up His kingdom on Earth as shown in Dan. 2:34-35.   However, it won't be the true Christians that are worshipping the beast's image; it will be apostate Christians and Islamic Muslims of an interfaith confederation or union with other religions.

Let us look at some anagrams below for some of these scriptures.

FOOLISH REIGNS is an anagram for "His legs of iron." (Dan. 2:33a)

PAPACY ODOR, FALSE INTERFAITH FRONT is an anagram for "His feet part of iron and part of clay." (Dan.2:33b) 

CRAFTY, PR0-INTERFAITH FOES DO A PLAN is a 2nd anagram for "His feet part of iron and part of clay." (Dan.2:33b)

FEAR THIS WEALTHY CONFEDERATION is an anagram for "His feet that were of iron and clay." (Dan. 2:34) (The wealthy confederation would be Islamic nations and Apostate Christianity represented by the Pope and the wealthy Vatican.)

WERT ADHERENTLY SHIA FACTION is a 2nd anagram for "His feet that were of iron and clay." (Dan.2:34)

In Daniel 2:41 the part clay in the feet and toes is referred to as potters' clay and then miry clay as shown in the verse below:

Dan.2:41, "And whereas thou sawest the feet and toes, part of potters' clay, and part of iron, the kingdom shall be divided; but there shall be in it of the strength of the iron, forasmuch as thou sawest the iron mixed with miry clay."

The Israelites were God's people and his elect and so are the Christians. So Christians could be the potter's clay as shown by 

Isaiah 64:8 which says, "But now, O LORD, thou art our father; we are the clay, and thou our potter; and we all are the work of thy hand."  Since the clay is now miry which can be muddy or dirty, it may mean a Christian who now as an apostate is soiled by sin that they haven't repented of. 

CRAFTY POPE ART LOST is an anagram for "Part of potters' clay" (Dan. 2:41b) (If the Pope is an apostate Christian who doesn't repent, he will be lost.)

FIT AN IRAN KINGDOM DEVIL BLOODSHEDDER PATH is an anagram for "And part of iron, the kingdom shall be divided." (Dan. 2:41c, d) (Shia or Shiite Islamic Muslims live in Iran, and their religion is known for beheading people with a sword.)

Below is another verse about the miry clay:

OH, U WHO ENDS EXTREME ISLAM - WAYWARD CHRISTIANITY is an anagram for "And whereas thou sawest iron mixed with miry clay," (Dan. 2:43) (We know that it is the Lord Jesus Christ who is the stone that smites the feet of the statue when He returns to end worship of the image of the beast by extreme Islamic Muslims who have a strong, rigid fanatical faith (the iron) and by wayward Christians who are apostates (the miry clay).

CHRIST BREAK, TRASH HEATHEN IDOL, END THE EVIL PLOY, NEGATED ANTI-CHRIST BEAST is an anagram for "And that it brake in pieces the iron, the brass, the clay, the silver and the gold; (Dan. 2:45b)
