They are all three dangerously delusional about Russian President Vladimir Putin.

Kissinger, the former U.S. secretary of state, has long sucked up to dictators and authoritarian leaders and pursued policies that killed civilians by the countless thousands. He needlessly prolonged the war in Vietnam and, recent allegations suggest, he may have had a hand in sabotaging Lyndon B. Johnson’s peace talks to get his patron Richard Nixon elected as U.S. president in 1968. He mourned the demise of the Soviet Union, rather than celebrated it, because it upset his twisted version of global superpower stability. So it’s no wonder he finds Putin a great guy with whom to meet — as he has frequently, according to Putin’s spokesman. Thank goodness he could never be America’s president.

But one who can, Republican candidate Trump, represents the worst of America — rich, crass, bigoted and ignorant. If, God forbid, he should ever be elected president, his foreign policy would depend on whether he likes a country’s leader or not. And if that leader, like Putin, flatters him, Trump is likely to ignore genocide, war crimes and all sorts of international crimes rather than pursue relationships based on rule of law, advancing world peace, a prosperous global economy and national interests.

Democratic candidate Sanders is the best of the trio, but he remains hopelesssly naive in his suggestion of a global security alliance that includes Russia, the current leadership of which promotes global instability. NATO members have no common values with Putin’s Russia.

The three exemplify varying degrees of American ignorance of foreign affairs, encouraged by isolationist sentiment in a nation that is so big and powerful that many of its 330 million people never leave its shores or bother to pay much attention to what is happening in the rest of the world.

The 2016 race simply doesn’t offer many good choices for Ukrainians or Americans.

Democrat Hillary Clinton’s reset with Russia as U.S. secretary of state was a naive failure and only emboldened and entrenched Putin. Her financial ties to Ukrainian oligarch Victor Pinchuk taint her. She has experience, but her judgment is questionable.

Bottom line: Ukraine should not count on the next American president being tougher on Putin or more helpful to Kyiv than Barack Obama, who has never made Ukraine a priority despite saying and doing the right things on a very small scale.
