President Donald Trump said he will meet with Russian President Vladimir Putin next Friday in Alaska to discuss ending the war in Ukraine, a potential breakthrough after weeks of expressing frustration that more was not being done to quell the fighting.

Whether the U.S.-Russia summit can lead to a deal to produce peace in Ukraine more than 3 1/2 years after Moscow’s invasion remains to be seen.

American officials quickly discovered a major snag in planning for the summit: summertime is peak tourist season in Alaska, and options both available and equipped to host the two world leaders were severely limited.
