What a refreshing burst of hawkishness from two top US political leaders.

At the risk of angering his base, President Obama on Tuesday abjured negotiations and boldly launched a preemptive strike against a menacing White House foe: musca domestica.

Obama whacked a housefly.

Bring it on!

That — natch — triggered the wrath of the flies-are-people-too folks.

Humans, “where they can be compassionate, should be, for all animals,” PETA spokesman Bruce Freidrich argued.

Meanwhile, Mayor Mike launched his own mini-offensive — against goose infiltrators from Canada.

“We are sending some of these geese for a well-deserved rest up in the sky,” Mayor Mike noted.

The birds are a genuine threat to civilian planes, and Task Force Bloomberg (spurred by a Post campaign) has moved to eliminate them.

Sure enough, Hizzoner also drew protests — but remained steadfast.

Now, if only Mike and the president would muster similar resolve against other enemies — you know, Iran, North Korea, al Qaeda . . . Albany, the Port Authority, pedicabs . . .
