Hmm... not really.

I mean sure Trump trying to align himself with this type of machismo is as pathetic as it always is.

... and yes the 300 spartans died while the persians did not die, so they were victorious in that sense.

However, the movie does try to push the narrative that those 300 spartans won an important victory because their death united the armies of the city states of greece to defend against the oncoming persian army.
