To the delight of America's enemies, presumptive President-elect Joe Biden is wasting no time in signaling a return to the oxymoronic and defeatist "leading from behind" foreign policy strategy of his former boss, President Barack Obama.

There are rumors the Biden administration will attempt to fix what isn't broken by rejoining the Iran nuclear deal the Trump administration abandoned in 2018 due to the agreement’s weak inspection and verification regime, automatic sunset provision and failure to restrict the Persian nation’s ballistic missile program.

With its top general killed by a U.S. military airstrike earlier this year and its economy under tremendous strain from American sanctions, the theocratic government of Ayatollah Khamenei is isolated both regionally and internationally.

A return to the nuclear deal by Team Biden — if the government if Iran would have them — would essentially be rewarding a theocratic state sponsor of terrorism in order to get back in the good graces of the amorphous global community.

On a related note, it remains to be seen if a Biden administration would lift a finger to help implement the Trump administration-brokered peace deals in the Middle East between Israel and Bahrain, United Arab Emirates and Sudan.

On another front, putative U.S. ally the European Union seems relieved that Trump will likely no longer be president after noon on Jan. 20, 2021, no doubt figuring probable President-elect Biden will be diplomatic putty in its hands compared to the combative and unpredictable Trump.

The friction between the U.S. administration and Europe was exemplified in Trump's making no secret of the fact that certain countries in the North Atlantic Treaty Organization were not pulling their weight financially, with Trump browbeating said countries in the alliance into committing to pay their fair share.

Nobody will be surprised if a President Biden backs off and lets Europe (and Canada) resume their penny-pinching funding efforts, leaving the U.S. to pay an outsized share for Europe's defense.

But it's China — the greatest threat to America and the world — where a Biden administration could do the most damage. After all, Biden has a long and well-documented history of being soft on the ChiComms. That image was buttressed by the New York Post's pre-election exposé on his son Hunter's emails revealing the family's questionable foreign business entanglements that the elder Biden has yet to unequivocally deny.

It seems unlikely that a President Biden would, as the Trump administration has done, aggressively confront China over its cyber-thievery and illicit trade practices in its quest for world domination. It will likely be back to business as usual — that is, talking tough on China while taking little or no action to check Sino ambitions.

In short, to America's detriment look for a return to a more conventional don't-rock-the-boat foreign policy that also includes rejoining the one-sided, U.S. economy-hobbling Paris climate accord and reversing the Trump-ordered pullout from the Chinese mouthpiece known as the World Health Organization.
