Just to update, if you are silly for worrying about it, then so are NATO, so you are in good company (from Al Jazeera):
NATO adjusting forces to counter ‘potential threats’
NATO is closely following developments in Iran and the Middle East, with their top commander in Europe adjusting forces as needed to defend against “potential threats”, the alliance said in a statement.
NATO’s Supreme Allied Commander Europe, US General Alexus Grynkewich, “continues to speak actively and regularly with military leaders on both sides of the Atlantic,” a NATO spokesperson said.
The top commander “has and will continue to adjust NATO’s very strong force posture to ensure the security of its 32 member nations and to defend the Alliance from potential threats, such as ballistic missiles or unmanned aerial vehicles, emanating from this or other regions,” the statement added.
