Share of research data


I was wondering. Since the US is acting very selfish in the past 4 years if the data that will be gathered, the research that will be discovered will be shared?

I am a bit reluctant to share my resources to a suppressing regime like the Trump regime that is only showing interest into exploiting others for their own gain.

My question: Is it guaranteed that the results the research finds is shared with the world or will it be kept for the US to use like many other things are currently kept for the US to use?

Thanks and excuse my concerns, but in Trump times I think these are justified worries.
