STORY: Key advisers to Donald Trump are publicly and privately floating proposals to end the Ukraine war that would cede large parts of the country to Russia for the foreseeable future.

That's according to analysis of their statements and interviews with several people close to the U.S. president elect.

The proposals by three advisors share some elements including taking NATO membership for Ukraine off the table.

His advisers would try forcing Moscow and Kyiv into negotiations with carrots and sticks including halting military aid to Kyiv unless it agrees to talk but boosting assistance if the Kremlin refuses.

Ukrainian President Volodymyr Zelenskiy has indicated that he may be open to negotiations.

But Trump may find Putin unwilling to engage, analysts and former U.S. officials said.

Taken together, the advisors' statements suggest the potential contours of a Trump peace plan.

They said it will likely depend on direct personal engagement between Trump, Putin and Zelenskiy.

There are three main proposals, a source said.

One is proposed by retired Army Lieutenant-General Keith Kellogg, Trump's incoming Russia-Ukraine envoy.

Another is from Vice President-elect JD Vance and the third advanced by Richard Grenell, Trump's former acting intelligence chief.

According to Kellogg's proposal, Ukraine would be offered U.S. security guarantees, which could include boosting weapons supplies after an accord is struck.

That plan could face blowback in Congress where some of Trump's closest allies oppose additional military aid for Ukraine.

Vance told a U.S. podcaster that a deal likely would include a demilitarized zone at the existing front lines that would be "heavily fortified" to prevent further Russian incursions.

Analysts say elements of the proposals would likely face pushback from Zelenskiy and his European allies.
