At the end of Succot we say the Prayer for Rain and on Passover the Prayer for Dew. The "we" is supposed to be all Jews, wherever one lives or is visiting. Inevitably there are questions by Jews who reside abroad, in galut, exile or more precisely chutz la'Aretz, outside of the Land of Israel aka Chu"L. They ask why they must pray for rain or dew when they personally don't need it.
There's a very simple answer to this, and it may bother or offend them. The answer is that the only location and weather a Jew must be concerned about is when it affects the Land of Israel, the HolyLand. The weather in Chu"L is spiritually irrelevant; it's not included in Jewish Prayers. We are the Jewish People, and we are supposed to be primarily concerned with our Land.
The Jewish Calendar, the timing of the Holidays and many of the Mitzvot, Commandments G-d gave us to observe concern and are connected to the Land of Israel, not any other.
Sorry, but there's no equality between various lands/locations. It's the HolyLand versus all others. In Creation, G-d separates, light and dark, water and dry land, and then a bit later on He gives instructions to Abram (as Abraham had been called earlier) to go לך לך lech lecha to the Land I (G-d) will show you:
Genesis Chapter 12 בְּרֵאשִׁית
And from then on the Bible concerns itself with the growth and development of the Jewish Nation and its relationship to the Land G-d gave us.
G-d sees us as one People wherever we are, whatever we do. When you read the siddur, Jewish Prayer Book, you're bound to notice that our prayers are in the plural. We pray to Our G-d. And even on Yom Kippur, when we confess sins it's in the plural.
(The "Al Chet" confession of sins is said ten times in the course of the Yom Kippur services: Following the Amidah of the afternoon prayers of the day before Yom Kippur; just before sunset on Yom Kippur Eve; and twice during each of the following services--the evening service of yom Kippur eve, and the morning service, the Musaf service and the afternoon service of Yom Kippur day--once at the end of the Silent Amidah, and once during the cantor's repitition of the Amidah.)We're in this "boat" together. So, please stay focused on the unity and the centrality of the Land of Israel.
For the sin which we have committed before You under duress or willingly.
And for the sin which we have committed before You by hard-heartedness.
For the sin which we have committed before You inadvertently.
And for the sin which we have committed before You with an utterance of the lips.
For the sin which we have committed before You with immorality.
And for the sin which we have committed before You openly or secretly.
For the sin which we have committed before You with knowledge and with deceit.
And for the sin which we have committed before You through speech. (continue)
