We have proven this and have presented its evidences. Its pictures are available; pictures of the Iranian regime that have recently entered Iraq. There is no doubt that the Iranian regime sends arms for killing Iraqis and the coalition forces. They also train and finance the very violent militia forces in Iraq.
