Malaysian flight to Beijing lost (MH370 CZ748) Why didn't the United States come forward to help China? And the EU, how is the EU?

There are several possibilities. It's been five days, and all the planes are out of gas. But I just can't find it. I can only say I miss you. This is a strange thing. This has happened before. 1980, another plane disappeared and flew back 35 years later. For Mh370. Probably because even the satellite can't detect it, it flew into the time tunnel, and another possibility is alien matter. Especially when flying at sea. It's easy to encounter these things. There is little chance of finding it. We can only pray. After all, we are from China.
