the Islamic State held in Syria as of March 18.

Can you see it?

It's here — just over a quarter square mile in size.

These are areas where ISIS launched attacks

since President Trump declared victory

over the Islamic State three months ago.

So what does this map tell us?

How did a group holding a tiny bit of territory

launch attacks across the country?

To deconstruct what this map shows,

we're going to start with some footage.

It shows ISIS members fighting to defend

their last bit of territory.

What do we see?

They're attacking with truck-mounted weapons

and assault rifles, taking cover behind buildings and trees,

moving through fields.

Now let's look at footage from

one of those far-flung attacks.

It's a bomb.

The blast killed 19 people, including four Americans.

The only ISIS fighter in sight, that we know of,

was the suicide bomber.

Here's the aftermath of another ISIS attack.

A suicide car bomb exploded

next to an American and Kurdish patrol.

So what this is showing us is that ISIS is adapting

the way it fights as it loses land.

From this, to this.

"The group has returned to its guerrilla warfare roots

while continuing to plot attacks

and direct its supporters worldwide."

And the frequency of all these attacks

shows that just because you've

squeezed ISIS into its last pocket of territory

by no means suggests that they'll just go away.
