The dramatic US strike, including the targeting of Iran’s most heavily fortified nuclear installation deep underground, marks the biggest foreign policy gamble of Trump’s two presidencies and one fraught with risks and unknowns.

Now that Trump has taken the significant step of entering the US in yet another Middle East war, where could things go from here?

"There is therefore no danger for the inhabitants living around the ... sites."
