If someone has tech to do interstellar trips in a reasonable time, we already lost any war against them.

The good news is, they probably don't need anything that we have, so the list of reasons to engage in war is kinda limited. Yay!

About communication, they would have an advantage understanding us, we are broadcasting into space for more than a century with radio signals carrying content of many of our languages.

The movie Arrival does an quite OK job showing how could be an effort to bridge the communication gap with aliens (besides the fiction), and is a good movie as well.
