Yes, Jews always participate fully in the life of the country of which they are citizens. Many congregations include a prayer on behalf of the country in Shabbat services. This prayer, from Mishkan T'filah, is especially appropriate as the United States celebrates its independence.
O Guardian of life and liberty,
may our nation always merit Your protection.
Teach us to give thanks for what we have
by sharing it with those who are in need.
Keep our eyes open to the wonders of creation,
and alert to the care of the earth.
May we never be lazy in the work of peace;
may we honor those who have died in defense of our ideals.
Grant our leaders wisdom and forbearance.
May they govern with justice and compassion.
Help us all to appreciate one another,
and to respect the many ways that we may serve You.
May our homes be safe from affliction and strife,
and our country be sound in body and spirit.
