The Daily Telegraph is now reporting, citing an unnamed source who is said to be close to the former president and current GOP frontrunner going into the November election, that Trump has developed a detailed plan for achieving Ukraine peace.

"There is a plan, but he's not going to debate it with cable news networks because then you lose all leverage," the source said.

Below is the section of the Friday Telegraph report which previews the plan: 

A source close to the Trump campaign has told The Telegraph that a detailed Ukraine-Russia peace plan has been drawn up but will not yet be disclosed in any detail before his in an effort to maintain leverage.

Mr Trump will style himself as the only candidate who can end the war, with a simple "bumper-sticker" slogan, they said.

"He wants to stop the killing," said the source. "That's the bumper sticker: Trump will stop the killing."

Last month a Washington Post report claimed that key to Trump's plan would be pressuring Kiev to permanently give up Crimea and part of the Donbas to the Russians.

The Post had cited aides who said the plan is to push for "Ukraine to cede Crimea and Donbas border region to Russia" in return for an end the Russian occupation and invasion.

But the truth is that at the very least Kiev would have to forever relinquish claims of sovereignty over Crimea. Moscow is also never going to let go to the four annexed territories in the east.

But Trump had slammed the apparently premature report as "fake news". At the time a statement from the Trump campaign said "The whole thing is fake news from the Washington Post. They're just making it up." Spokesman Jason Miller did emphasize, however, that "President Trump is the only one talking about stopping the killing. Joe Biden is talking about more killing."
