The German is optimistic about his side's chances in Brazil, while Clint Dempsey also believes USMNT can go a long way in the tournament
The Americans get their campaign up and running on Monday as they meet Ghana in Natal, but they face an uphill battle if they are to get out of the tough Group G.
The clash with Ghana is followed by games against Portugal and Germany, both of whom will be fancied to make progress to the knockout stages.
However, Klinsmann is in high spirits and optimistic ahead of their opening match and the 49-year-old believes that the American public are right to expect big things this year.
"I booked my flight home after the final," he said at a press conference.
"Expectations now in the United States are very high.
"We are growing not only on the international level. The domestic league is more and more competitive, in every area the game is growing. We want to drive this as the locomotive, as the national team.
"No matter what the circumstances are, no matter how the game goes, this group is ready to make it happen.
"Whether it is snowing or thunder and lightning, this is about playing football.
"There is nothing better than starting against a team that beat you in the last two World Cups. There is nothing like starting the World Cup like it's a final."
Clint Dempsey, meanwhile, echoed the coach's thoughts regarding what should be expected of the Americans, insisting there is no reason why they cannot remain in Brazil until well after the group stage if they play to their capabilities.
"Every time you come to the World Cup it's a fresh slate," he said.
