Is there a way to view KML natively in ArcMap?

Most KML/KMZ readers store the features in the Geodatabase for viewing. Arc2Earth seems to be the best way to read and write KML/KMZ so I'm not sure there is much of a problem converting back and forth.

Interoperability Extension will read KML/KMZ natively - http://www.esri.com/software/arcgis/extensions/datainteroperability/index.html (it is basically FME in ESRI clothing) - at extra cost of course - ESRI should make it standard with the software.

This is an old post. pretty easy import as follows: arcmap 10.x > arc toolbox > conversion tools > from kml > kml to layer. drill down to the kml file. specify the output file and it will magically appear in your map as an editable layer.
