The Irish Rugby Football Union (IRFU) believes it was let down by Scotland and Wales in its unsuccessful bid to host the 2023 Rugby World Cup.
Ireland received just eight of the 39 votes on offer in the first round of voting in London Wednesday, and were dropped from the next stage where France's bid prevailed.
"We're very disappointed that Scotland and Wales didn't support us," IRFU chief executive Philip Browne said.
"I think Scotland said they were consistent in that they said they were going to vote for the bid that produced the greatest amount of money and Gareth Davies was part of the evaluation process and I think the Welsh Union felt duty bound to support Gareth. But that damaged us, significantly.
"Every union has its own objectives and its own strategies, and that was Scotland's."
Browne was also critical of World Rugby, questioning the governing body's motives.
"The reality is, if it is all about the money then new hosts like Ireland really shouldn't be involved with it at all," he said.
"We put up a really strong financial bid that matched South Africa, but France is a big country and they put a lot of money on the table.
"If its simply about money and shiny new stadia well then obviously there is no room for Ireland.
"World Rugby has a vision that it's going to be a global sport, at the moment one has to question whether that vision is really backed up by the sort of criteria that was set down in relation to this bid."
Ireland rugby legend Brian O'Driscoll tweeted that he was very disappointed but proud of the effort that went into Ireland's bid.

Cian Healy -- who is in Ireland's current squad -- also took to social media to say he was "gutted" Ireland didn't win the vote but hoped his country would head to France as title defenders.
Wednesday's vote means the World Cup and Olympics will be held in the same country in consecutive years once more with Japan holding both sporting events in 2019 and 2020 respectively.
