An article by Gov. John Kasich (R) in Foreign Affairs will only increase speculation that he’s laying the groundwork for another presidential bid:
Although American leaders should always put American interests first, that does not mean that we have to build walls, close off markets, or isolate the United States by acting in ways that alienate our allies. Continuing to do that will not insulate us from external challenges; it will simply turn us into bystanders with less and less influence. I choose cooperation and engagement. Only those who have forgotten the lessons of history can credibly contend that peace and prosperity await us inside ‘Fortress America.’”
