The ability to travel to another galaxy would put you in the same
technological league as the grey aliens and all other ET species who have
attained 'FTL' travel.  But the technology is such that it can not be
attained by a species which is driven by emotion rather than intelligence.

Well you need intelligence to create the technology of interstellar travel.
Likewise for creating a jet engine or anything sophisicated.
Interesting it's the designers that are intelligent - not the leaders
who determine how such technology is to be used.

Correct.
