it's not that we are in violation, it is that we are presently unable to fulfill many mitzvos in the Torah.
We still fulfill several hundred of the 613. One day, we will again fulfill the rest.
Torah Jews are still obligated to intensely study the laws of sacrifices and the Sanhedrin etc.... even though it has benn almost 2000 years. many tractate'so of the Talmud deal with these.
certain mitzvos are only applicable in the land of Israel, so some mitzvos and laws have become relevant again since the early 20th century when Jews started repopulating Israel again. Although the commandments have always been required here, they were barely applicable since so few Jews lived here for 2000 years.
