The U.S.-Russia summit in Alaska is happening at a site where East meets West in a place familiar to both countries as a Cold War front line of missile defense, radar outposts and intelligence gathering.

The threats, pressure and ultimatums have come and gone, but Russian President Vladimir Putin has maintained Moscow’s uncompromising demands in Ukraine, raising fears he could use a planned summit with U.S. President Donald Trump to coerce Kyiv into accepting an unfavorable deal.

What’s emerged from the Washington-led effort to end the war in Ukraine suggests a deal that seems likely to be favorable to Russia.

Ukraine’s consent to a 30-day ceasefire proposal has handed the Kremlin a difficult challenge at a time when its military has an upper hand in the war.

The arrests began last month when a Russian deputy defense minister was detained.
