US soil within a week... interesting... It's damn impressive for China to gather the resources and equipment to bypass US defense systems, including the vastly superior USAF and naval systems, plus 5,000 miles of ocean (Bering Strait doesn't count, as it is impractical for military purposes). Even a week of uneventful preparation isn't enough. If the US and China went into a direct Pacific conventional conflict, it would be in the middle of the ocean if anything. Plus... in terms of alliances, China works alone for the most part, thereby eliminating treaty obligations. Chin does what it wants, basically, but the US has NATO, and the combined projection of power would ti the balances far in NATO's favor.
