Megan Bowman, a law lecturer at King’s College, London, said the four-year waiting period was partly intended to insulate the agreement from a shift to a Republican presidency after Democratic President Barack Obama.
“The downside … is that if they (the United States) are recalcitrant they are sitting at the table, able to…
