President Donald Trump travels to US Central Command on Monday, meeting officers who will form the tip of the spear in implementing his new strategy to defeat the Islamic State group.

After a three-day break in southern Florida, Trump will stop off at Centcom headquarters in Tampa on his way back to Washington.

The military command is responsible for an area that includes the Middle East and Central Asia.

It plays a key role in Operation Inherent Resolve -- the US-led mission to "degrade and defeat" the Islamic State group -- which has resulted in 17,861 strikes across northern Syria and Iraq since August 2016.

Apart from seizing territory and declaring a caliphate, the Islamic State group has claimed responsibility for attacks in Africa, Europe, the United States, Southeast Asia and across the Middle East.

It's seen as influencing attackers in San Bernardino, California, who killed 14 people in December 2015, and the attacker of an Orlando nightclub, who left 49 dead in June last year.

In late January, Trump ordered generals to begin a 30-day review of the US strategy to defeat the Syria and Iraq-based militant group.

Trump had made fighting "radical Islamic terrorism" a central plank of his election campaign and the issue is emerging as the organizing principle of his foreign and domestic policies.

He used potential cooperation in the fight against the Islamic State group as a reason to embrace Russia and has tried to implement an order banning refugees and nationals of seven Muslim-majority countries from entering the United States.

The ban has spurred an unprecedented battle with the courts. On Sunday, Trump tried to pin the blame for future attacks on the federal judge who blocked his executive order.

"Just cannot believe a judge would put our country in such peril. If something happens blame him and court system. People pouring in. Bad!" Trump said.

He did not offer evidence for the suggestion that would-be terrorists are flocking to the country.

Most experts express more concern about Americans becoming radicalized and carrying out IS-inspired attacks, rather than the group dispatching clandestine agents around the world.

Hundreds of Trump's own diplomats have voiced their opposition to the ban.

- Taking the fight to ISIS -

The contours of Trump's policy to fight the Islamic State group abroad are still coming into focus.

On January 28, he signed a presidential memorandum that called for a review including any "recommended changes to any United States rules of engagement."

That could foreshadow a tougher approach, but it is one that some experts believe could fuel radicalization.

During Trump's first days in office, US special forces carried out a raid against Al-Qaeda in Yemen which resulted in the deaths of one US soldier, 14 jihadists and as many as 16 civilians.

Trump also called for the "identification of new coalition partners" -- a likely nod toward Russia.

Moscow has deployed aircraft, naval assets and troops to Syria, but has so far trained its fire on rebels with the aim of propping up Bashar al-Assad's regime.

After substantial territorial gains, IS is now on the back foot, struggling to hold onto the Iraqi city of Mosul and with its "capital" in Raqa under threat.

But the battle is approaching a fork in the road.

Trump has reportedly shelved his predecessor Barack Obama's plans for taking Raqa with the help of Kurdish forces and must soon decide how to proceed.
