If you find a prior-filed trademark abroad, would it block your commercial use in the U.S.?

In the U.S., trademark rights are primarily established through actual use of the mark in commerce within the U.S., not just by registration in a foreign country. Generally, if a foreign company has no commercial presence or use of the mark in the U.S., their foreign use and registration do not automatically grant them rights that would block a good-faith U.S. user or registrant.
