Shalom,
Could you please explain these concerns I had with your post:
1. Do you measure whether G-d is with a nation, by how powerful their military is as a "super power"?
2. How will the "Romans" recapture anything?
1) The earth belongs to Allaah, He gives it to those who are Just, and He will grant it to the believers - the same way He gave the kingdom to Prophet David and Solomon once they strived, sacrificed and showed their sincerety in Allaah. We are going through a similar stage, we will face hardship and trials like the children of Israeel until we fully submit ourselves to Allaah, then He will grant us victory and a huge reward, in this life and the next. But He will only grant it when He knows we are truelly worthy of it.
Allaah says in the Qur'an:
"Allah has promised to those of you who believe, and do good deeds, that He will surely grant them in the land inheritance of power as He granted it to those before them; that He will establish in authority their religion which He has chosen for them. And that He will change their state after fear to one of security and peace. They will worship Me alone and not associate aught with Me." (Qur'an Al-Noor (the Light) 24:55)
And also: "Say to those who deny faith, soon you will be vanquished." (3:12) and "When comes the help of Allah and Victory, and you see the people enter Allah's religion in multitudes . . ." (Qur'an Al-Nasr (the Divine Support) 110:1-2)
2) The Romans are the Europeans, the prophecy of capturing Constantinople [Istanbul] was already prophecised by the Messenger of Allaah (peace be upon him.)
The Prophet, upon him be peace and blessings, told his community that they would conquer Damascus, Jerusalem, Iraq, Persia, Istanbul (Constantinople), and Cyprus, and that Islam would reach as far as the easternmost and westernmost parts of the world.
Recorded in Hakim, 4:445; Ibn Hanbal, 4:303; also related by Muslim, Tirmidhi, and Ibn Maja.
He thus foretold the conquest of Istanbul by Muslims, and indicated the high spiritual rank of Sultan Mehmed, the Conqueror, and the virtuousness of his army. What he foretold took place centuries later.
The stage we are in right now has also been prophecised:
"The Prophethood will last among you for as long as Allah (God) wills, then Allah would take it away. Then it will be (followed by) a Khilafah [caliphate] Rashida (rightly guided) according to the ways of the Prophethood. It will remain for as long as Allah wills, then Allah would take it away. Afterwards there will be a hereditary leadership which will remain for as long as Allah wills, then He will lift it if He wishes. Afterwards, there will be biting oppression, and it will last for as long as Allah wishes, then He will lift it if He wishes. Then there will be a Khilafah Rashida [guided] according to the ways of the Prophethood," then he kept silent.
[Recorded in Musnad Imam Ahmad (v/273)]
Allaah knows best, but it may be that Turkey may get into the European Union, and therefore it may become part of the Roman Territory. However, it will return back to the muslims once again. Only when Allaah wills.
