While statements from Mr Trump remain broad and lacking in specifics, he has confirmed he is not willing to put boots on the ground after a peace settlement.
However, more than 30 European countries have made this pledge.

The UK, alongside the European Union, are understood to be preparing to implement new sanctions on Russia if Vladimir Putin refuses to attend talks with Mr Zelensky and Mr Trump.
A senior Government source said: "If Putin was to delay, prevaricate, or refuse to talk that would provide another impetus for sanctions."
White House Press Secretary Karoline Leavitt said both the Russian and Ukrainian leaders had expressed a willingness to engage in direct talks.
However, Anders Fogh Rasmussen, who led the Nato alliance from 2009 to 2014, argued that Mr Putin is just playing for time has no real intention to end the war.
He told the Ukrainecast podcast: "President Putin is not interested in peace.
"That's why he convinced President Trump not to let a ceasefire be the first point in the peace process, btu go directly to peace negotiations."
Mr Rasmussen added: "Europe must take its destiny in its own hands.
"Ant I think the first important step in that direction would be to drop a reassurance force to Ukraine."
