Of course it may happen that becoming more visible in the universe would provoke impossible to defeat enemies against us. But the argument for this is purely hypothetical and one could similarly make an argument that sitting around on our rock and not expanding could end in us being wiped out (cf.: Every primitive culture on Earth ever wiped out by explorers/settlers). It seems impossible to decide which way is safer with our current information, so I'm for expanding/exploring till we know more.
