The choice we face is just as stark when it comes to our national security.

Anyone reading the news can see the threats and turbulence we face.

From Baghdad and Kabul, to Nice and Paris and Brussels, to San Bernardino and Orlando, we're dealing with determined enemies that must be defeated.

No wonder people are anxious and looking for reassurance. Looking for steady leadership.

You want a leader who understands we are stronger when we work with our allies around the world and care for our veterans here at home. Keeping our nation safe and honoring the people who do it will be my highest priority.

I'm proud that we put a lid on Iran's nuclear program without firing a single shot – now we have to enforce it, and keep supporting Israel's security.

I'm proud that we shaped a global climate agreement – now we have to hold every country accountable to their commitments, including ourselves.

I'm proud to stand by our allies in NATO against any threat they face, including from Russia.

I've laid out my strategy for defeating ISIS.

We will strike their sanctuaries from the air, and support local forces taking them out on the ground. We will surge our intelligence so that we detect and prevent attacks before they happen.

We will disrupt their efforts online to reach and radicalize young people in our country.

It won't be easy or quick, but make no mistake – we will prevail.

Now Donald Trump says, and this is a quote, “I know more about ISIS than the generals do….”

No, Donald, you don't.
