Will the absence of the US on FWC 2018 affect the position of MLS?

Major League Soccer vs FIFA World Cup 2018

The constant presence of the American national team at the FIFA World Cup has always had a positive impact on the USA brand recognision as a "football country", indirectly also affecting the attractiveness of the MLS perception. The lack of the US presence in Russia may undermine this image. However, if we look at the numbers - there is no bad. 19 MLS players participate in Russia (mainly from Panama, Mexico and Costa Rica). In Brazil in 2014 - there were 21 of them, with the USA Team in the tournament.
So, no doubt the strength of the MLS goes up. However, the question is open - whether the absence of the USA at FWC 2018 will not harm the MLS position in the future?
