In short, the answer is partially yes. Part of Iraq was inhabited by the ethnic tribes that are known today as Persians by the Western world and Parsi in the Iranian language. The other portion of Iraq was occupied by the Sumerians/Babylonians, which was ruled by a tyrant, known as Nebakanezer. Once Cyrus the great unified the nomadic tribes that inhabited modern day Iran, parts of Afghanistan, Pakistan, Turkey, and Iraq, under the Persian banner, he then entered into Babylon (Iraq) with no resistance, freeing the Sumerian and the Jewish people. The Persian/Parsi is a culmination of the following ethnic groups: Lurs, Elamites, Medes/Kurds, and allegedly Armenians, according to Greek text.
The city-states of Athens and Sparta joined forces along with the other southern Greek city-states to defeat the Persian invasion in 480-479 BCE, however they were not enemies - they were allies before and after the Persian invasion. Sparta had offered support to Athens against the Persian attack on Athens a decade before that, and Athens supported the Spartans when Messenia revolted against Spartan rule twenty years after the Persian invasion. Not exactly enemies. They became enemies when Athens set out to dominate the Greek world, resulting in the Spartan-led Peloponnesian League and Athens and its new empire clashed in a destructive Peloponnesian War 431-404 BCE. Athens lost, was stripped of its empire and became a second rate power.

Iraqis are made up of several different ethnic groups, with the overwhelming majority being Arabized Mesopotamians. They are genetically distinct from the Arabian Arabs of the Arabian peninsula and maintain consanguinity with the inhabitants of Babylon and Assyria. The only reason they're labeled Arabs is because they speak the Arabic language which was introduced to Mesopotamia during the Islamic conquest in the 7th century. Minorities of Iraqis are from other ethnic groups, such as Kurds, Assyrians, Chaldeans, Alevis, Turcoman (also spelled Turkmen), Azeris, Yazidis, Shabakis, Mandeans, and Persians, and there used to be an Iraqi Jewish population before the 1970s.
An argument for an allied invasion of France before 1944 was that quicker Hitler was forced to fight two fronts the quicker he would be defeated. An argument against an allied invasion was that it would be too expensive and risky.
No it was a suprise attack
In 490 BCE in the Plain of Marathon and the same day before the walls of Athens.
First King Agesilaus I of Sparta, but he was recalledto deal with troubles in Greece. Then King Philip II of Macedonia, but he was assassinated before he could get his invasion going. Then his son Alexander III (the Great) who successfully took over the Persian Empire.
No one. Athens organised its empire in the aftermath of the Persian invasion. Sparta minded its own business. None of the other city-states were in a position to dominate anyone.
King Philip II of Macedon prepared an invasion but was assinated before he left. It was continued by his son King Alexander.

The Battle of Salamis involved the Persian Empire - it was part of the invasion led by King Xerxes to try to bring the Greek city-states under control to stop their internecine warring spilling over into his empire.
Having subdued his opponents in mainland Greece and elected Hegemon of Greece, Phillip II of Macedon wanted to stop the Persian interference in Greek affairs and exact payback for the Persian invasions in the 5th Century BCE (and incidentally of course gain an empire). He was assassinated before he set out, and his son Alexander carried out his father's plan.
Before the Mongol invasion, Chinese officials were selected through civil service exams. After the invasion, this system was eliminated.
Alexander's father Philip, expanding the Macedonian empire, called up Persia's invasion of Greece, over a century earlier, as a propaganda reason to take on the Persian Empire. Philip was assassinated before his departure on the campaign and his son Alexander took it over.
the life there was normal before the nazi invasion. they were allowed to practice their religion to their God before the nazi invasion.
The turning point was the defeat of the Persian fleet at Salamis the year before, which saw the naval threat to the Greek cities ended and enabled them to send their armies to Plataea to unite instead of being kept at home trying to defend their cities, and half the Persian army sent home as there was no food for it in the winter without a fleet to supply it. Plataea saw the defeat of the reduced Persian land force and ended the invasion.
The question as put is unanswerable. There was no "invasion" of Palestine.
