Any thought of it? Personally i don't think it will be practical due to sheer distance between the stars and i don't think warp drive is possible...

The nearest star is what? 4,5 lightyears away? This means interstellar war is improbable, or at the very least, very much an all-or-nothing effort. There won't be reinforcements. There won't be the possibility of retreat. It's do or die. Transit times are simply to long for reinforcements to arrive in a timely manner. Any message you send won't reach your homeworld for years to come. The same goes for trade. I'm willing to believe interplanetary trade and war is possible, but not interstellar trade/war. The timescales are to vast to turn a profit or benefit from your conquest. Dismantling asteroid belts and planets for the construction of a Dyson swarm seems much more credible than interstellar warfare. Furthermore, space appears to be empty of other civilizations, so there won't be any obstacle to colonization.

Yea sheer distance from star do make interstellar war or trade unbeneficial, and i can't find any good that can allow trade between star happen due to extremely high cost of transportation. |

its too far, it would take decades of travel to make it from two nearby stars, and then their is no retreat, if you really want I'll give you R-Bombs across intersetller distance

yes you don't even need payload, just mass

if you have enough mass you have a planet cracker

or moving very, very fast That "fast" speed may require antimatter and wrap drive , and i think that they are very VERY unlikely jump out from the fiction books in the future... |

You could also use Nicoll-Dyson beams.
If relativity-compliant wormholes can be created (something not forbidden by known physics, though it's not the same than it being possible), here is an example of non-Kardashev levels:

Note the part about causality warfare

Well it will requirement a huge amount of power and really large mirror (Maybe around ~thousands km wide) and prefect aiming system... |

You don't need a really large mirror, you can make do with millions of smaller mirrors. If you have a perfect dyson swarm, all you have to do is make everything with mirrors on one side of the star shine the reflection toward a single point in the sky, and you have a laser with half the power of the star. It's a bit more complicated than this because there will realistically always be overlap and losses and such, but it's perfectly possible without needing gigantic mirrors. |

Maybe, but i just doubt if human need all these thing before the sun dead/too large to make earth and mars unhabitable... |
