I highly doubt that the US would have ever joined the war on the side of the Germans - they were making far too much money selling arms and ammunition to France and the UK. Not to mention the fact that most of the people who fought in the Civil War were dead and buried. That, coupled with the near constant British efforts to ingratiate themselves with US administrations (like siding with the US over Canada on the Alaskan Pandhandle dispute), made it very unlikely that the USA would ever have sided with the Central Powers.
And while the USA was a rising power, it couldn't have broken the Allied blockade of Germany by itslef, as France and Britain had far larger and more powerful navies during the war.
In the 1910 US Census German-Americans and Irish-Americans together formed the majority of the US population. That particular segment of the US populace was not so terribly enamored of either the UK or of France. While there was a commercial relationship do note that trade should not be mistaken for friendship. Prior to both world wars German and France were each others #1 trading partner and the US was Japan's #1 trading partner prior to WW2.
That the US and Britain were important trading partners did not preclude the USA from sitting out the war (as it did for most of it) or joining the Entente. President Wilson was keenly aware of British espionage in the US and an incident in the Washington Navy Yard of 1912 involved British nationals and was a minor scandal of the time.
The two most important things that swung US opinion to the Western Allies were the sinking of the Lusitania (which history now shows was a valid target for the Germans) and other attacks on passenger ships and then the Zimmerman telegram that was interecepted by and passed to the US by British intelligence.
That the US did not build a major navy for WW1 had to do with the fact that the German Navy was bottled up and controlled by the Royal Navy.
We had the industrial capability at the time to build a larger navy but it would've been senseless to build a massive navy to fight what was principally a land war by 1915. As it was, the battleships that the US sent to join the Brits in 1918 mostly just tooled around burning oil.
As to the Alaska Panhandle issue, the Brits more or less did cede the territory in return for improved relations with a rising industrial power whose Pacific Fleet at the time was more than a match for the Royal Navy that operated only from Esquimalt in the Eastern Pacific. Obviously, this action paid off some years later when the Brits needed the US for supplies and food during WW1.
