...the reason I said that is because your posts seemed to imply that the poem was primarily about the narrator’s personal plight, not his identification with anything bigger .

The poem is primarily about the narrator's own plight.It's an efficient dialectic the poet puts across here.Remember that his unraveling is triggered, by implication, by a media hyped reports of a coup in the Middle East, cause of the turmoil not disclosed. It sets the tone for the rest of his day, which he was obviously anticipating with dread. After he is saturated with the alienating currents of the memorial service, he returns from the local to the global, witnessing angry televised protests, feeling it as rage about to spill over or explode from the box containing it, and recognizes at once that he isn't the only one who feels like this. He indeed does relate to something larger than his own unease; he realizes the discomfort is shared, the rage is same whatever the language.
