That would depend solely on how many Konoha ninjas survived the explosion and remained in any condition to fight soon. But it's naturally true the country's general power level will be deemed lower by others as soon as they hear of this. Yet not all of them would be willing to amass their forces and march out knowing there's an unpredictable entity out there that could decimate even Konoha - and they could be the next victim for all they know. Also the fact Konoha still sports a bijuu hasn't changed. That alone would probably keep any smaller enemies away.
