Problem: Under the leadership of Vladimir Lenin, the Bolsheviks established the Soviet state on 7 November [O.S. 25 October] 1917, immediately after the Russian Provisional Government, which governed the Russian Republic, was overthrown during the October Revolution. Initially, the state did not have an official name and wasn't recognized by neighboring countries for five months. Meanwhile, anti-Bolsheviks coined the mocking label "Sovdepia" for the nascent state of the "Soviets of Workers' and Peasants' Deputies".
For how long did the Soviet Union go unrecognized?
The answer is the following: five months

Problem: Federal law and treaties, so long as they are in accordance with the Constitution, preempt conflicting state and territorial laws in the 50 U.S. states and in the territories. However, the scope of federal preemption is limited because the scope of federal power is not universal. In the dual-sovereign system of American federalism (actually tripartite because of the presence of Indian reservations), states are the plenary sovereigns, each with their own constitution, while the federal sovereign possesses only the limited supreme authority enumerated in the Constitution. Indeed, states may grant their citizens broader rights than the federal Constitution as long as they do not infringe on any federal constitutional rights. Thus, most U.S. law (especially the actual "living law" of contract, tort, property, criminal, and family law experienced by the majority of citizens on a day-to-day basis) consists primarily of state law, which can and does vary greatly from one state to the next.
What is day-to-day, operational law considered?
The answer is the following: "living law"
