they are well equipped
They would be tough to face for weak armies. They need to been taken out before they grow too big.
There is no doubt that they are well-equipped. However they are mainly equipped with secondhand weapons. They are just using whatever they can lay their hands on. Secondhand weapons are not an unlimited stock. Eventually, they will run out of weapons which they can take from the people they defeat. Eventually, they will not be able to defeat everyone they meet. For example, when they face the Peshmerga, they are not able to just walk in and take the weapons.
The main issue here Aree is that they always seem to be getting new or used equipment, so they have to be financed by someone or else they would not be able to continue this war.

So a nation can't be behind it.
This is not the case. Syria and Iraq have abundance of small arms. That is enough for multiple years. ISIS largely relies on small arms/suicide attacks. The issue is that they seem to have access to material to create these suicide bombs and car bombs. There is also black market for small arms sales in that region. So a nation can't be behind it.
Maybe not one nation. Most probably a lot of nations. I did read that the situation there is very much a war fought by proxies. There are countries there which are against each other, ideologically, like the Shias vs the Sunnis. So the Shia countries are arming one side while the Sunni countries are arming the other side. Covertly, of course.
Today they do and have largely ended arms shipments.
A lot of weapons were left behind Iraqi army possibly from raided military bases.Looks like someone has left behind a lot of lethal weapons in the hands of people who abandon the weapons at the slightest sign of danger. Or did the ISIS buy those weapons?
