(CNN)Donald Trump may have just torched his last real friend in the Western alliance, someone he could have counted on when the going gets tough. In what was supposed to be a frank exchange of views, French President Emmanuel Macron apparently got the full Trump treatment the other day when he tried in a phone call to level with the one world leader who does not support being leveled with, even coming from his closest confidants.
And with a succession of battles looming on the trade front, on Iran's nuclear future, on migration and climate change, not to mention a dicey North Korean summit in Singapore, Trump needs all the friends he can get. Now, Trump seems to be flying entirely solo, as Macron, long an apparently reliable wingman, peels off, reaching a long-awaited, though not unexpected, reconciliation with his principal challenger for European leadership -- German chancellor Angela Merkel.
The saddest part of all is that Trump apparently failed to even comprehend the context. Macron and Merkel, who herself has had a pretty frosty relationship with Trump, have been getting decidedly chummy themselves recently.
But there are other issues that should be even more troubling for Trump in Merkel's statement and Macron's phone call. Merkel now sees such a joint military force as a way of keeping Britain involved in Europe's defense and the United States very much on the periphery.
At the same time, a European Union summit at the end of June, following this week's G-7 summit in Canada and Trump's meeting with North Korean dictator Kim Jong Un next week in Singapore, promises a whole new set of challenges that Washington is barely prepared to take on, and indeed seems only to be intensifying by the day.
Of course, little of this rhetoric appears at all congruent with what President Trump has been proposing for the United States -- far more restrictive immigration policies, few grants of asylum and virtually no coordination with foreign allies or partners on such issues, not to mention a border wall that remains in a state of suspended animation.
And then came the phone call between Trump and Macron -- focusing, as a subdued White House statement observed, on trade and immigration, as "both leaders discussed the migration problem in Libya, and timelines to solve it. President Trump underscored the need to rebalance trade with Europe." As it happens, the call took place the same day the administration announced its decision to levy stiff tariffs on European steel and aluminum exported to the United States; Macron said the decision was "not only illegal, it is a mistake on many points." Now there is the overhanging threat of European retaliation, none of which seems to have been in the least eased by the Macron-Trump phone call.
Moreover, the Paris climate agreement, from which Trump withdrew the United States early in his presidency, will also be on the table, not to mention a central question as to whether the final communique will suggest, as it did last year, that the G-7 is really the G-6 plus Donald Trump's America -- yet another testimony to "America First" being very much America alone.
Still, President Trump should practice diligently in front of a mirror his best smile -- the kind he was so eager to trot out for his Oval Office session with North Korean emissary Kim Yong Chol, bearing the cartoonishly-large envelope with a letter from Kim Jong Un -- and suggest that he is at least prepared to listen to reasonable voices even if he thinks he really knows best. For America does very much need friends in Europe, as well as north and south of our own borders.
