Firstly, you're wrong...
Not all Uchiha can suppress the Kyuubi. Amongst the Uchiha there are only a handful that have the Genjutsu strong enough to keep the Nine tails under their control. Notice how every time the Kyuubi is being controlled... the first thing anyone thinks is Madara? Madara is always noted as the ONLY Uchiha capable of controlling the 9-tails. While this is far from true. No one believes it's a common trait. Even Danzo needed the first hokage's cells in order to have enough chakra to even think about subjugating the 9 tails.
Madara, Obito, Itachi(Presumably) and Sasuke(Presumably). Itachi, i assume because he is noted to have the harshest genjutsu strength in the manga. And Sasuke we've seen control the other tailed beasts all at once so assuming he can control only the fox is a no brainer.
Being able to control the fox isn't some passive all Uchihas have. Only a dozen of the Hundreds of Uchiha are known for their genjutsu as the top 1% of Shinobi. And even less have the Chakra pool capable of handling the Kyuubi effectively. And even less of them have the skill to be able to completely smother out the Kyuubi's raw power and make it completely theirs.
""Hiruzen to not allow them in the front line so Hiruzen told them to do only resuing stuffs.""
^-Umm
And my policing statement wasn't 'dumb' you literally repeated what i said. You stated uchihas were responsible for rescuing the citizens... aka police work during a disaster. So you agreed with me but insulted me? It almost feels like you simply like to disagree with me because you're bored.
Lastly. Link. I've read 4 flash backs of the Attack and Nowhere did Danzo tell the 3rd to hold back the Uchiha. The shinobi who fought during the attack were barely highlighted because it was mostly about Naruto and his family. Iruka's parents and a few of the parents of the current gen were shown in their last moments. But no one ever said an Uchiha was NOT in the fight.
The Senju weren't shown during the attack... do we assume they weren't there? The Hyuuga weren't shown in the attack... do we assume they weren't there?
So unless you can show a link that specifically shows Danzo telling the 3rd to not let Uchiha fight the Nine-tails, you just made that point up.

Secondly,
Good god you are daft. This is easy at this point.
Alright. The Second seperated them, not physically but he set up a system to make them hate each other.
He gave them control of the police force, knowing that people would soon dislike the Uchiha, and the Uchiha would become conceited and make everyone around them feel belittled. This promoted dislike in the village. This combined with the placement of the police headquarters forced Uchihas to move to the outer village.
The 2nd never physically made them move. He just set up their living situation, and fanned the flames of dislike between them and the Senju, so they would casually separate. Like water and oil after you shake up a bottle. Sort of Genius.

Thanks for that Link.
However Danzo + the Elders actually FORCED them to move into a corner of the village.
Kyuubi Attack
Camps - (Top left panel) Notice it was AFTER the attack, they were 'forced' into the living quarter.
There is the distinction. You can try to word shuffle out of this one but your own link killed your own point.
The 2nd never separated them, i gave that point to you thinking you knew what you were talking about.The Uchiha moved away from the Senju who disliked them for being the police and being too prideful. It was their decision.
Danzo on the other hand used actual physical means and intimidation to force them into a living quarter of the village.
Under the 2nd they might've been disliked because of racism towards them. But they at least had the ability to come and go as they pleased. But Danzo forced them into a single spot with no freedom and watched them daily. You cannot honestly believe those two are the same situation?
So in short:
Tobirama make mistakes by pushing Uchiha outskirt of the village and making a police force comprise only of Uchiha and buliding there hideout next to the village prison.
- Yes. I agree he made mistakes here. And just so we're clear, you know it is their POLICE headquarters and not their homes correct? He didn't push them out of the village. They decided to move because they weren't wanted in the village.
When Hiruzen succeded he failed to see those things and take any actions to prevent any ill feeling. He remain ignorant of everything and he even fueled their rage by not allowing them to a battle to save there village like some outcast.
-Again, he wasn't even in power when the Kyuubi attacked. He was retired. And no where in the manga did Danzo specifically tell ANYONE not to let the Uchiha fight in the battle. You made this up unless you have a link. Show me one and i'll apologize. But you don't have one so this is moot.
He could have control that if he was open to the villagers and make an excuse about why he didn't allow uchiha in the battle. By annoucing that it was he who didn't allow the uchiha, atleast it will help people to not question Uchihas and thereby lowering the possibility of enemity.
-Again the 4th Hokage gave out the orders to the Non-Anbu of this time period. If the Uchiha weren't allowed to fight, it'd be because Minato said so. The 3rd was retired during the Kyuubi attack.
And another Caviote. Danzo convinced the Elders. The Elders are stronger politically than the Hokage. Stop talking abotu what you clearly have no clue about. It's shown even when Tsunade is in a comma that the Fire Daimyo is the one who picks and keeps the Hokage in place. The Elders serve under him, and Danzo had influence on the both of them. So yes, the Elders are more important than the Hokage politically. And if they wanted to bad enough, they would replace him.
The Third did try. He voiced against discrimination of Uchihas actively. Even when Danzo and the elders were placing them under surveillance and plotting to murder them. He fought them at every step. He lacked the political power to stop them. You just see what you want to see. You honestly think he'd sit back and let it happen if he could give the order against it? He politically cannot. The Fire Daiymo's elders are above him. He was the one that allowed itachi to be an AnBu. A position that before the 3rd was NEVER given to Uchiha. But the third allowed him to become one in order to try to build trust with the Uchiha.
But what did the Uchiha do? They saw the Third Hokage give them a position of power, and demanded the Itachi spy for them so they could kill the 3rd hokage and everyone who was in power.
Again i agree with you... Prevention is better than a cure.
So why didn't the Uchiha back down after Knowing their two strongest fighters turned their backs on their cause... and continued to threaten to kill the whole village? Why didn't they understand that even if they all fought... they couldn't beat Itachi, so why continue the plan and risk the lives of their children?
