President Trump's fulminations against foreign terrorists is standard White House talk. The presidents Bush, father and son, used similar rhetoric, laced with doses of Christian fundamentalism. And winding back a generation, when I left high school, President Kennedy was fanning a global war on communism in Indo-China. He and his successor, Lyndon Johnson, were bullying allies like New Zealand, seeking canon-fodder. There was even talk of sending conscripts from here. Now that was scary.
Over the following decade, the United States plus friends laid waste to Vietnam and its neighbours. It didn't just target individual homes. It rained down flaming napalm - jellied petroleum - on whole villages. The survivors found their fields and surrounding jungle, poisoned dead by cancer-causing, plant-killing defoliants, sprayed from above.
Trump alluded to this back story over the weekend in defending his overtures to Russia, arguing the US cannot claim moral superiority over its old foes. When Fox News' Bill O'Reilly protested that Russian president Vladimir Putin was a killer, Trump countered, "There are a lot of killers ... What do you think? Our country's so innocent?"
The highly respected journal Foreign Policy says not. In 2013, it published a list of seven governments the US has officially admitted to helping overthrow since 1953, when the CIA, with the backing of Britain, overthrew the elected government of Iran after it nationalised BP's oil assets. Between then and 1973, when the CIA backed General Augusto Pinochet's coup against Chile's elected socialist government of Salvador Allende, the USA also overthrew the Guatemalan Government on behalf of a US-owned fruit company, and backed coups in the Congo, Dominican Republic, South Vietnam and Brazil.
Then the other "adventures" such as Iraq, Afghanistan and several other countries south of the border Trump now plans to wall off.
True, Trump is an aberration as far as US president's go. But it's not because of his embracing the global war on terrorism that the US has been engaged in for decades. His uniqueness lies in his delight in discarding all the usual diplomatic mumbo jumbo.
That one of the first victims of this new openness was Australian PM Malcom Turnbull and his shameful backroom refugee swap deal with Obama, was an unexpected bonus. Maybe he isn't all bad.
