I believe it was Iraq who lost more...The reasons are:

1- Iran has 3 times more population than Iraq, and did use a tactic called "human wave", using her huge population and sacrificing the people, even women and children, but Iraq had invested in technology, and paid a lot to use technological weapons bought from USA and Europe,and even Soviet Union..Therefore, fell into a great amount debt pit after the war...Iran was more likely to compensate, but Iraq wasn't able to compensate the debts.

2-The Gulf War, which definitely weakened Iraq with all its aspects, occurred due to the results of Iran-Iraq War.Kuwait refused to delay put off the Iraqi debts and Iraq invaded.

3-The fractions in Iraq, like the Shiites or Kurds got more restless after the war due to instability that the long-lasting war had caused.

4-The Sunni Muslim countries who had egged Iraq on to get rid of the radical Shiite danger of Iran had deserted Iraq after the war, of course by requesting what they had given to Iraq during the war

5-One thing to be mentioned is that both sides getting definitely NOTHING at the end of the war...Neither sides gained anything and lost a lot, so it is a war that didn't give any profit to any sides.The winner of that war was definitely the countries who had the most benefit out of this war was the countries who sold weapons and equipment to those countries and some Sunni Muslim countries who supported Iraq and reached their aim of weakening Iran at least for a bit and a while.

I remember reading that out of the 700,000 dead (approximate figure) in the Persian Gulf War, 400,000 were Iraqis (again approximate figure). I cannot remember the source, sorry, and of course it dose not include wounded, missing and prisoners.

both countries lost a lot, but here is why iran lost more, yet still managed to bring about a stalemate:

1) the whole of teh western world supported iraq with weapons (chemical and biological), money, logistics, training, satellite imagery, and by using their navies (USA) of keeping iran from manuevering in the Persian Gulf. the Arab world funded iraq with billions of dollars.

2) Iran, with no allies and barely any help, had to resort to some drastic measures, using its population.

3) after the revolution, iran had disbanded the army, and the mullahs had executed many generals and soldiers.

All i can say is thank God that the shah stockpiled so many US weapons before the revolution. with out those, iran would have definetly lost.

iran had more casualties and infrastructural damage, therefore it lost more in the short run, but iraq lost more in the long run due to their debt.

Definitely...Mullahs strengthened their regime due to war...People of Iran had to consider about the Iraqi threat of invasion instead of regime, and by that way, Mullahs' regime strengthened.

It was more because of Iran's tactic of "human wave",sending even women and children to the front to form huge numbers in the fight.That's why Iranian casualties were more.

The help of those "a lot" of countries to Iraq later was costly for Iraq,showing its effects till today. 

Saddam was retarded in that when he invaded he declared that he was going to annex Khuzestan and didn't lie and say he wanted to depose the mullahs.  Immediately all Iranians united to defend the nation, when Saddam could have caused old regime loyalists to join him in his campaign to depose the mullahs.  They would have noticed his duplicity only when it was too late.

first of all, women were never used in these human wave attacks, however children under the age of 18 (probably 15-18, supposedly volunteers, accompanied by older men ofcourse) were used in human wave attacks.

i dont even think women were used as soldiers at the time.

but this  was all due to the fact that iran didnt have the support, help, and technology iraq was given.

no, iranians would have fought to death for the regime in 1980.

the anti regime sentiments started after the war. and iranians would have defended their country no matter what, whether it be fighting for the mullahs or whoever else. iranians dont like their country being invaded.

even today, all the anti mullah spokesman that want the US to invade iran are considered traitors in iran by the public. that is the same reason why the MKO followers are considered traitors.

I understand ur hatred for the mullahs but to blame everything on the mullahs is a bit extreme. Did the mullahs start the war? who did the mullah fight to win? It is about the war. If there was a power vacuum that only the mullahs could fill then y blame them for doing so.

What do u think is happening in Iraq, power vacuum and <---mullahs in power.

A lot of the common people would have fought to the death, no doubt, but a few traitors in high places would have helped Saddam a great deal.

they did, they are called the MKO, the most hated people in iran. if you ask the general public about what they think of the MKO (traitor pigs!!!) they would say that they need to be killed!

the MKO are the most hated in iran because they betrayed iran in its time of most need.

According to what I know, women were used in the frontline. My source is a famous Turkish political history professor, Fahir Armaoglu, who had made his doctorate at Harvard University,but of course, that doesn't mean every stuff he says is true

There wer female brigades but they were not on teh front lines.

Iran certainly paid a much higher price for the war, but in military terms, it was also a clear victory for Iran. Iraq did not achieve any of its stated objectives, and in fact was put into the position of defending their own territory at one point. Iran, on the other hand, fulfilled all of the objectives of any defender: to retain ownership of their land, drive the war back onto the enemy's territory, and punish the attacker. They also established their reputation for defence, while Iraq only established the fact that even given a technological advantage its forces were not capable of succesful aggression against comparable powers.

A pyrrhic victory to be sure, but clearly a victory for Iran nonetheless.

the fact is that everyone in the world knew that iran would have crushed iraq.

the USA knew, western europe knew it, the USSR knew it.

when iran pushed iraq back after 2 years and then proceeded into iraq itself, the rest of the world got worried.

iraq was about to collapse, so the west and the USSR started helping iraq militarily, financially, logistically, etc....

iraq would have lost but in order to keep the balance of power in the Persian Gulf region they helped iraq.

what? pst. the 15 million dollars worth of guns the USA gave us. what BS is that?

yea, a lot of help iran got. 15 million dollars, ONCE, compared to the billions iraq got in logistics, technology, military equipment, funding, etc...

No, not really. They supported Iraq much much much much mcuh much more, all they did was sell us kalashnakovs.

I remember propaganda pictures from teh time showed Iranian soldiers wmarching over three flags, British, American and USSR.

nope, one of teh most famous chants during the revolution was " we dont want the west, we dont want the north (USSR), all we want is islam"

no one helped iran, why cant you guys admit that.

for iranians, we have already fought WWIII.
